What exactly is voltage?

The total voltage you get from one out and back, even with a high temperature difference is pretty small. By putting many of these out and back combinations together, you can get a useful voltage. A single

How are current and voltage related to torque and speed of a

Voltage instead "regulates" how fast a motor can run: the maximum speed a motor can reach is the speed at which the motor generates a voltage (named "Counter-electromotive force")

LED forward current vs forward voltage

I am trying to make a simple circuit for a nametag for kids to solder at a workshop. The LED I was planning to use is 151033BS03000 it has a graph of forward current vs forward voltage.

Why does the voltage drop across a given resistor change when I add

Why exactly does the voltage drop in R1 change when I add another resistor to the circuit? I understand that it has to change according to Ohm''s Law (V = IR), but how does the amount of charge moving

How to allow smaller clearance between two specific high-voltage nets?

Because there is never a voltage difference between them, I would like the clearance between these two specific nets to be only 0.2 mm, while still keeping 0.6 mm clearance between

inductive

The reason the voltage across the motor dies away slowly is because in the absence of current driven through it, it becomes a generator. That is, the spinning rotor has momentum, and

What, exactly, is voltage?

And also if voltage is like gravitational potential energy, how does more voltage mean more current? And here our nice analogy breaks down. In this sense voltage is more like pressure in

What do the plus and minus symbols on an independent voltage

This most recent experimental setup yields a varying voltage, mostly influenced by triboelectric charge generated by clothing-in-motion flowing through the voltmeter''s high resistance

What is "forward" and "reverse" voltage when working with diodes?

The reverse voltage is the voltage drop across the diode if the voltage at the cathode is more positive than the voltage at the anode (if you connect + to the cathode). This is usually much

Volts vs voltage

As I have understood it voltage is electric potential difference while volts are just electric potential. So I can say that the negative end (ground) of a battery has many volts since there''s a lot...
