What, exactly, is voltage? - Electrical Engineering Stack Exchange
Aug 22, 2020 · 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 exactly is voltage? - Electrical Engineering Stack Exchange
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 …
What do the plus and minus symbols on an independent voltage …
Feb 8, 2026 · 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 …
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
Is there a maximum forward voltage limit for diodes like the 1N4007?
Apr 16, 2025 · The voltage across the diode itself is proportional to the logarithm of the current through it. You don't get to control both the current and the voltage, independently. So as the forward voltage …
inductive - DC motor voltage kickback when turning off - Electrical ...
Mar 4, 2024 · 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 …
How to allow smaller clearance between two specific high-voltage nets?
Dec 27, 2025 · 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 …
Relay Voltage Transient: Releasing Coil to NC vs. GND and With vs ...
A high voltage arc will dissipate the energy in the coil very quickly. The higher the voltage, the quicker the dissipation. A comment by Tim Williams points to the fact that one of the non-idealities of a relay …
Volts vs voltage - Electrical Engineering Stack Exchange
Jul 30, 2015 · 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...
How are current and voltage related to torque and speed of a …
Sep 3, 2012 · 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") …
