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 …
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 …
What, exactly, is voltage? - Electrical Engineering Stack Exchange
Aug 22, 2020 · I'm 15 and recently started electronics and I'm having trouble understanding voltage. I've read so many articles and watched so many videos about voltage and they all …
Practical example of controlled voltage and current sources
Dec 2, 2023 · In text books some controlled or dependent voltage and current sources are shown. What are they really? Can someone explain them with real examples?
What exactly does "common-mode" mean in the context of op …
That article talks about the common-mode input voltage of an opamp, that is, the signal that is common to both the inverting and noninverting terminals (which is ideally rejected).
Three phase power supply - what is line to line voltage
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
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 …
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 …
