Potential energy, basically

>>10762345
Electrons hate each-other because they are all so alike, when you put too many together they want to leave to someplace without electrons like some type of goddamn hipster garbage. If you make a path that they can travel they will scoot and that's a current. The more there are of them the faster they will try to shove themselves down the path you made. This is disgusting and also what voltage is.

>>10762348
I'll add to this. If you are going by the fluids analogy, voltage is analogous to hydraulic head.

>>10762345

You know why every single physics book starts with block on an inclined plane then moves to Gm1m2^/r^2 then to carnot cycle then to ' which direction would the B field be if the positive electron was launched right ways in this tube' then to then to 'find the parallel capacitance of this circuit' then to optics then to radioactive decay and finally to quarks?


Its moving from BIGGEST to SMALLEST

>>10762345
You have a massive dam full of water and empty river, big voltage STONK resistor!!!!

>>10762348
not exactly, but it's the best analogy someone can come with

>>10762353
Pumps are Voltage sources.
Resistors are smaller pipes.
Capacitors are pipes with a balloon stretched across them.
Inductors are turbines attached to flywheels.

muh d incres ur mum voltage ;^))))

>>10762361
That's why I said "basically." Voltage is the potential energy per charge.
If you lift up a mass off the ground, that mass will have some gravitational potential energy which will tend to send it back to the earth. If you "lift" a piece of charge (you can think of an electron, but this isn't so physically accurate it turns out), it will have some potential energy per unit charge, called VOLTAGE, which will tend to send it to the ground of the circuit.

I WANT TO FUCK THAT BUNNY SO BAD OMG I NEED TO FUCK THAT BUNNY PLEASE GIMME SAUCE I CAN LITERALLY SEE HER BRA COMING OFF OH GOD OH FUCK DUDE JUST PLEASE HELP ME I NEDD NEED NEED NEEDD NEED TO FUCK THAT BUNNY FUCKKKKKK

>>10762368
That's how Eurasian cuties make me feel.
Feels good to not want to fuck small furry anthropomorphized animals.

>>10762368
doxy is the source you fucking pervert

>>10762384
THANK THANK THANK YOU THANK YOU THANK YOU THANK YOU, IM GONNA GO FUCK THE BUNNY NOW

>>10762345
It's the difference of potential energy per charge between two points.

Why does a resistor make the voltage drop?

Joules per coulomb

>>10762345
Its best imagined with pipes and water. Imagine a pipe, a vertical pipe, and water flowing up, maybe a fountain, the pressure that is pushing the water is voltage, same way the electron flow is pushed. With a wire imagine a single electron traveling along the wire, why does it move, because something is pushing it, thats voltage, if voltage drops your appliances wont receive electrons and will stop working. Also a slightly more advanced way of thinking is pressure differential, at the beginning (A) of the pipe pressure is higher than at the end, so the liquid or the electrons will flow from higher pressure to lower

>>10763605
For the same reason there are pressure losses in a long pipe. Energy/voltage drops when a flow/current posses through the rough surface/resistance of the pipe/resistor.

>>10762345
Voltage is velocity of a moving object.

>>10762352
Haha

>>10762345
it's literally the same mathematical object as pressure. they work the same way because that's where the inspiration for the concept of voltage came from.

Voltage IS defined via potential energy

the first answer is the best one by far

>>10764324

that's wrong. it's defined via potential energy and "normed" to a charge

>>10764337
>Voltage IS defined via potential energy
That's exactly right. The voltage between two places A and B tells you how much potential energy will be converted to kinetic energy if a charge particle moves between between A and B (or how much kinetic converted to potential)

The "electron volt" is a unit of energy which explains this very nicely.
