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 …
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 …
What is the difference between line and phase voltage?
Jun 26, 2025 · 2 In a three phase system, I’ve heard line voltage described as the RMS of the voltage difference between two lines coming from the power source and phase voltage is RMS …
Why does the voltage drop across a given resistor change when I …
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 …
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 …
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 …
How to allow smaller clearance between two specific high-voltage …
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 …
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 …
How much voltage/current is "dangerous"? - Electrical Engineering …
Likewise, if the current and voltage are below a certain level, a person can--given enough time--safely absorb an arbitrarily large amount of electrical energy. Further, if voltage is sufficiently …
What is "forward" and "reverse" voltage when working with diodes?
Mar 3, 2011 · 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 …
