  1. 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 …

  2. 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 …

  3. 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 …

  4. 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") …

  5. 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 …

  6. 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 …

  7. 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...

  8. 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 …

  9. operational amplifier - Voltage controlled current source design ...

    Oct 25, 2024 · I'm working on a project where I need to design a bipolar current source controlled by a sinusoidal voltage between -1.25 V and 1.25 V. It has to deliver a maximum bipolar sinusoidal signal …

  10. What is the difference between \$V_ {CC}\$, \$V_ {DD}\$, \$V_ {EE ...

    Jul 26, 2011 · Obviously order is important, since for two points in the circuit A and B, V BA = -V AB. Bibliographic reference: If the same letter is repeated, that means a power supply voltage: Vcc is the …
