Nice Webkinz🀦. This is just straight up incorrect. A volt measure voltage/electric potential/potential difference. Power is typically measured in watts. A watt is equivalent to voltsΓ—amperes or joules per second. A volt is equivalent to joules per coulomb.

I genuinely think the potential of hydrogen fuel cells is much greater then electric cars

Now I could be wrong but it sure seems like in North America if you're not on team Elon you're a traitor. I am all for the idea of electric vehicles, I'm all for a greener future. Yet I feel like people as we always have just turn a blind eye to the bad. Currently there is a ton of waste happening with the batteries in electric cars. The mining of lithium is just terrible all around. Even in Toyota's tundra release they opted for a nickle battery. This definately isn't the better battery, but they stated the materials are much easier to acquire and they can better recycle these batteries, so good on them I suppose.

I think what I'm getting at is that for me in North America everyone is going electric. I've even seen many threads of people hating on companies not pushing electric but trying different maybe better solutions. I honestly think hydrogen is a much better alternative. Yes currently it uses to much fossil fuels to be created. Still now that more money is being thrown at it people are finding better, more efficient ways to produce it. At least from a vehicle standpoint I see hydrogen as having a much greater potential then electric. Am I crazy to think that?

Why electric potential decreases in a uniform electric field?

I know that E=-dv/dr.Assume that i brought a particle near a charged plate of infinite area(E=Charge Density/2*Epsilon).Both the particle and charge have same polarity,the charge repels away and its electric potential keeps decreasing with distance.When it reaches zero, the force should not act on it (conservative force). BUT here is a catch, the formula shows that the electric field does not decrease with distance so the force should be non zero.

I am confused by the definition of electric potential due to a point charge in my Physics book, need some clarification and help!

Here is the link to the definition in question: https://imgur.com/a/U1KEN7B

What I have understood thus far is that there exists two points A and P joined by a line. Charge Q exists at point A. We seek to find the potential caused by this charge Q at point P

However here is where my confusion starts. They have started that AP = r, and that r = infinity
Therefore I think it is implied that AP = infinity in length therefore A and P are separated by a distance of infinity

Would this not mean the potential at point P is thus 0? The charge Q is infinitely far away and thus should have no effect on the potential at P. They then proceed to say that a test charge q is moved from r = infinity to point P

H..how does this make any sense? I have been trying to think this through for so long and I just end up tangling up my brain cells. Point P is ALREADY at infinity, so what does it even mean to logically bring a point from r = infinity to a point already at infinity? Aren't we basically moving a point from infinity to infinity here? What does that statement even mean?

I am thoroughly confused by these two issues. I would be very grateful if someone could clear these doubts of mine

Electric Heating Potential Cost

Hi,

I have a viewing scheduled at the end of the week for a two bedroom mid terrace house without mains gas.

Unfortunately, the local gas supplier has already confirmed that they wont be able to make a new connection due to the distance from the main pipe.

The house ticks a lot of boxes on my requirements list but I am very concerned about the potential electricity bills. If you have any experience of living in a similar property, could you please share how much you were paying? This would really help me decide if I want to make an offer on the property I am going to view.

In the figure particles with charges q1 = + 6e and q2 = - 16e are fixed in place with a separation of d = 23.9 cm. With V = 0 at infinity, what are the finite (a) positive and (b) negative values of x at which the net electric potential on the x axis is zero?

The problem: https://imgur.com/uVCjff6

My work: https://imgur.com/9a5T6Tx (answers are in meters)

This is a tricky one to explain. I got the correct answers eventually by using the work shown above, but I had to flip some signs.

The work on the left was supposed to be for positive X axis. For q1 and q2 I used positive numbers in the final formula both times. This is because when I set the two potentials equal to each other, one had a positive charge and the other had a negative charge. Therefor, when I moved the negative charge to the other side of the equation, the value mathematically became positive. However, I did something wrong here and I'm not sure what. The value I was supposed to wind up with was ~.065. I can get .065 by simply using -16 for q2, but I don't understand why I have to do that.

The work on the right is for the negative X axis. Same exact reasoning as above, all charge values are positive in the final equation. This one is correct without me having to change any signs. What gives?

Edit: Upon further inspection, I realize that because r is negative in the second part of the problem, the actual equation I need to use to find the answer is the equation on the left (which gives me the correct sign as well). But wouldn't this just mean that the first and second parts are solved with the same equation? "r2" should be (r - d) in both cases, no?

I'm not sure how to visualize electric potential.

Relevant: https://imgur.com/1F0eEW4

I thought I could imagine it similar to normal potential energy. Positions of high potential energy correlate to high electric potential. So an electron placed close to a positively charged plate would have low electric potential, but a proton placed in the same position would have high electric potential. But this seems to be wrong?

For example, one of the problems assigned to the picture above is: "For which pairs is there a point at which Vnet = 0 between the particles?"

I figured that the answer must be 3 and 4, as their forces act in the same direction and could keep a particle in equilibrium in between the charges. If you were to put a charged particle on 1 or 2, the particle is pushed in the same direction by both original particles. So it would find it's equilibrium point somewhere off to the side.

But apparently this is an incorrect way of thinking. The actual answer is the exact opposite, and I'm not sure why. I'd like to how I'm supposed to visualize electric potential.

How is it possible that electrons lose Electric Potential Energy to heat and light in a lightbulb?(electron flow current)

The amount of Electric PE an electron β€˜q’ in a circuit has is: U= k (qQ)/r

So if we keep q and Q constant (hypothetically, there are no other electrons in the circuit, so Q is constant), the only way U changes is if the electron gets closed.

So how does the Electron β€œlose” energy to factors OTHER THAN its distance from Q?

If there is a way other than quantum mechanics or relativity to explain this, please explain that way. If there isn’t, use one of the 2 theories because I’m confused still.

First timer. Potential apartment says residents are responsible for gas, electric, cable, internet, water. I have a few questions

As I mentioned Im a first time renter so these are probably going to be stupid questions. I realize for things like cable/internet each renter will go out and find their own service. But how does gas, electric, and water work? Is it something that all tenants in the complex have the same set up for? Is it something Ill just have from the get go and then (depending on how much I use) itll be added onto the monthly rate? Or do I also have to go out and find my own service for?

Im curious how it all works but Im also trying to find a ballpark estimate of how much this will add to my rate. Most places Im looking at are slightly under $1,400/month. My GF and I are splitting it so if its $700/ea per month this falls below the 30% rule not including the utilities (combined income is 75k). Place also has a dishwasher and washer/dryer

For question 1, I said that the two charges are the same sign, and I assume they have to be equal in magnitude because that way they can repel each other and make r to infinity for electric potential to be zero.

For question 2, I think that the other point is only on the right side of q2 because it can be another P point like the one on the left side q1 for electric potential to be zero because in between a point for two similar charges would make the equation V = 2kQ/r which will not be zero.

Just wondering if I am correct with what I have reasoned. Thank you in advance for the help! (:

Another potential beneficiary of the Biden infrastructure plan - PTRA (electric drivetrains for busses / commercial vehicles)

Yes PTRA has already de-SPAC'd but I figured this would still be an appropriate place to discuss it given it was one of the hot EV-related SPACs of recent times.

Anyway, PTRA (Proterra) is a company that makes EV powertrains and charging infrastructure for commercial vehicles, particularly busses (school busses, normal adult busses, every kind of bus you could ever imagine). They will eventually also electrify other types of commercial vehicles.

Beyond the general "biden is giving money to EV busses" here is what makes things interesting to me on PTRA:

  1. they are a realer company than most other EV SPACs or recently IPO'd companies. They are expecting to do $400m+ of revenue next year, expecting to grow that to $2.5b in 2025 (but of course that is their own investor deck, so take that with a grain of salt). but with $7.5b in free money for electric busses and more for related infrastructure, that is certainly going to help accelerate adoption. Right now PTRA has an enterprise value of perhaps $3.5 billion, so it's not any kind of value stock, but they're actually up and running, making real substantial revenue, with positive gross margin, and have a great tailwind that will soon be in their sails. 9x revenue isn't all that bad when Tesla goes for twice that.
  2. i didn't put this in the title because it is a getting to be a tired trope, but yes, there is short squeeze potential here. There are ~5m shares shorted which is 5-10 days to cover depending on which average volume number you use (NASDAQ had 500k/day, Yahoo finance has closer to 1m/day, i'm sure they use different timeframes). Cost to borrow is up to near 100%. This is likely due to the fact that they're one of the not that many remaining ex-SPACs that are still a fair bit above the deal price (they're $18 as of this moment) but shares were as high as $30 following DA.

So how to play it? I own some shares and I also have some July $25 calls in case it does become a meme / short squeeze anytime soon. But I am comfortable owning it for the long term and will add in much greater size if it instead sinks back towards the deal price.

Potential cheeky new strategy that I'm calling 'The Electric Blender'

I've been reading through the rules, and I think I've found a cheeky little strategy you can use

Requires: 1 Techpriest Artisan, Electropriests (Corpuscarii may be better, for reasons I'll cover), some way of reliably getting them into close combat. A transport would be ideal, but considering they have a +5 invulnerable save and a 5+FNP they're tankier than you'd think

So let's say you've managed to get your Artisan and their coterie into close combat. Since they're electropriests, if they were the ones who charged you get the Voltagheist Blast ability.

>Voltagheist Blast: After this unit finishes a charge move, select one enemy unit within Engagement Range of this unit and roll one D6 for each model from this unit that is within engagement range of that enemy unit. For each 6+, that enemy unit suffers 1 mortal wound.

(Note that it doesn't say unmodified 6+ there, which is nice.)

Here's where the fun part happens. Once it is your movement turn again, you want to fall back to the minimal distance outside of engagement range. Because your Artisan techpriest has this initial ability:

>Enhanced Biomechanical Interface: At the end of your Movement phase, if this part is active for this model, select one friendly <FORGE WORLD> CORE or <FORGE WORLD> KATAPHRON SERVITORS unit within 6" of this model. Until the start of your next Movement phase, that unit is eligible to charge and shoot in a turn in which it Fell Back, but if it does so, each time a model in that unit makes a range attack, subtract 1 from that attack's hit roll

Bam, your electropriests can immediately charge and Voltagheist Blast again! But in addition, Corpuscarii have this ability:

>Motive Force Sight: Each time a model in this unit makes a ranged attack, you can ignore any or all hit rolls and Ballistic Skill modifiers

So if you're using Corpuscarii you can shoot at your full BS, in addition to then charging again for another Voltagheist Blast.

If your army is Ryza and your Artisan has the Citation in Savagery Warlord Trait, I can see this being even better.
