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 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 …
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 …
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 …
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 …
How much voltage/current is "dangerous"? - Electrical Engineering …
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 …
Why does reactive power affect voltage? - Electrical Engineering …
Why does reactive power influence the voltage? Suppose you have a (weak) power system with a large reactive load. If you suddenly disconnect the load, you would experience a peak in the …
How are current and voltage out of phase in capacitive circuit?
Jan 21, 2013 · We say that in capacitive circuit the voltage and current are out of phase. Current is 90 (degrees) ahead of voltage. What is the physical explanation for this effect? How can …
voltage - Help me understand the relationship between positive ...
Some circuits need a negative voltage, so the positive side of a battery would be "ground". Some circuits need positive and negative voltages, in which case there could be two batteries, one …
