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, 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 …
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
power - RMS voltage/current vs Average voltage/current - Electrical ...
Jan 27, 2026 · When the voltage is fixed, as at the supply voltage and transistor collector, then the true power is proportional to the (average) current times the voltage, since there is no squared term …
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 …
Understanding Voltage and Current Phase Difference
May 10, 2025 · 1 I am having trouble understanding the concept of voltage and current having a phase difference in AC circuits. I have recently begun exploring AC circuits and have just started delving …
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") …
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 is usually much …
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 …
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...
