  1. 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 …

  2. 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 …

  3. 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 …

  4. How much voltage/current is "dangerous"?

    6 It's not the voltage but the current that kills, is a popular yet still incorrect incomplete answer. It is the ENERGY that kills. With static electricity you will will be exposed to voltages much, …

  5. Difference between Working Voltage and Isolation Voltage?

    Feb 12, 2022 · The isolation voltage is just the rated maximum between two galvanic systems that are supposed to remain isolated. Just think of it as insulation, like what surrounds an insulated …

  6. Understanding Voltage and Current Phase Difference

    May 10, 2025 · But the capacitor defines the voltage over resistor in an RC series circuit, because the capacitor voltage changes based on the charge it stores, and how the voltage changes …

  7. voltage - What is the difference between Vrms and Vm? - Electrical ...

    I am relatively new here and I am confused as to the difference between Vrms and Vm. I would be obliged if someone can explain. (This in relation to 3-phase circuits would be even better) My …

  8. RMS value calculation of 3 phase line voltages for power calculations

    Apr 27, 2021 · You can use either but you have to remember that the phase to phase voltage is times the phase to neutral voltage. The term just comes from the trigonometric relationship …

  9. Voltage drop across a single resistor and across two resistors

    Jul 20, 2020 · An intuitive way to look at is that all the voltage is dropped across two resistors, and since the resistors are the same, the voltage drop across each will be the same, each taking half.

  10. Reducing voltage with resistors - Electrical Engineering Stack …

    Sep 2, 2014 · As others have mentioned you can use a voltage divider of two resistors, but the voltage divider output will change if the load current changes. You can still use a voltage …
