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 …
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, 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 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 …
Why are voltage and current inversely proportional to power, but ...
If power is a constant, then, yes, current and voltage are inversely proportional since power is their product. Again, this has nothing to do with Ohm's Law. Ohm's law says that voltage and …
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 …
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.
Different voltage sources in parallel - Electrical Engineering Stack ...
Apr 11, 2019 · I realize connecting two different voltage sources in parallel is a contradiction (in an ideal circuit). But if I were to connect this in practice and measure the voltage across points A …
current - How to measure battery voltage during charging?
Jul 2, 2024 · Will I read battery voltage/charger voltage/intermediate voltage between 15V and 12V. How do we get the exact battery state during charging to show the battery percentage in …
