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 …
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 …
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 …
How much voltage/current is "dangerous"?
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 exactly does "common-mode" mean in the context of op …
Most, or maybe all, topologies could end up outside of common mode voltage ranges at some specific time. What is important is to understand under what conditions will you be outside of …
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 …
How to calculate voltage drop over and power loss in wires
How do I calculate the voltage drop over wires given a supply voltage and a current? How do I anticipate on voltage drop so that the final load has the correct supply voltage? What will be …
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 …
What does a voltage or current source actually output?
Mar 17, 2024 · Voltage is the cause, current is the effect. So both sources provide a voltage on their terminals. In the voltage source the voltage on the output terminals has, or is intended to …
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 …
