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") …
TVS Diode Clamping voltage less than breakdown voltage
Nov 27, 2024 · Clamping voltage where if the voltage at the source continues to increase (e.g. due to a momentary surge) then voltage across your load will remain at this clamped voltage and the TVS …
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 have, a …
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 …
Why does a resistor reduce voltage if V=IR? [duplicate]
According to Ohm's law, resistance varies directly with voltage You should read this the other way. Voltage varies directly with current. "R" is the constant of proportionality telling how much it varies. If …
What exactly does "common-mode" mean in the context of op-amps?
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 the common …
Why are voltage and current inversely proportional to power, but ...
If power is a constant, then, yes, current and voltage are inversely proportional since power is their product. Again, this has nothing to do with Ohm's Law. Ohm's law says that voltage and current are …
Zener diode forward voltage - Electrical Engineering Stack Exchange
3 I'm trying to learn how Zener diodes work and I think I get the overall concept (regulating voltage to the zener voltage level), but there's one thing I don't understand. I'm looking at this diode and see that …
voltage - "Ground" vs. "Earth" vs. common vs. negative terminal ...
Aug 4, 2014 · Voltage has exactly the same problem: one terminal can only "have a voltage" when compared to another terminal. Voltage acts like distance: voltage and distance are double-ended …
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.
