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 …

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") …

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 …

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 …

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 wire. That …

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 with the …

Dec 4, 2013 · 2 Line to line voltage for a 3phase network (120deg separation) is sqrt (3)*phase voltage. So for a 230V 3ph network the line-line is 400V

Jan 20, 2021 · Yes, because I is a function of V, as long as we're talking about resistors. Power is linearly proportional to voltage, though, if you're talking about a constant current device.

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, much, much …

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 …
