What, exactly, is voltage? - Electrical Engineering Stack Exchange
Aug 22, 2020 · We say that voltage is like pressure, or like gravitational potential energy, because we're trying to draw an analogy to something that you can see or feel (because you can drop a …
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 …
inductive - DC motor voltage kickback when turning off - Electrical ...
Mar 4, 2024 · The reason the voltage across the motor dies away slowly is because in the absence of current driven through it, it becomes a generator. That is, the spinning rotor has …
power - RMS voltage/current vs Average voltage/current
Jan 27, 2026 · (1) the emitter resistor is a linear device so any voltage across it is time proportional to the current through it. This means that there is complete harmonic compatibility …
Voltage of Incandescent Christmas Mini Bulbs [closed]
Dec 18, 2023 · The simplest solution is to wire an incandescent lamp in series with your lights. The smaller the wattage, the higher the resistance and the more voltage drop you'll get. The …
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 …
Why does power supply have a negative rail if can only output …
Jun 4, 2024 · According to the datasheet of this power supply, the output voltage goes from 0~60 VDC. If the output can't be negative, why does it have a negative rail beside ground?
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 …
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.
