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") …
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 voltage. A single …
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 …
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 low, the …
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 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 …
Does LED brightness change with voltage?
Sep 6, 2016 · The voltage only needs to be slightly above the forward voltage rating of the LED. A common way to control brightness is through pulse width modulation (PWM). Instead of giving a LED …
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.
What is the difference between "reverse stand off voltage" and ...
What is the difference between "reverse stand off voltage" and "breakdown voltage" on a TVS? Ask Question Asked 12 years, 11 months ago Modified 2 years, 5 months ago
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 shot at
