- 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 out and back is called a thermocouple, and can be used to sense temperature Many together is a thermocouple generator Yes, those actually
- What is the difference between line and phase voltage?
2 In a three phase system, I’ve heard line voltage described as the RMS of the voltage difference between two lines coming from the power source and phase voltage is RMS voltage of a particular line relative to the neutral (0 V)
- How are current and voltage related to torque and speed of a brushless . . .
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") which is equal to the voltage it receives from battery (disregarding power losses and frictions for simplicity)
- voltage - Vb and Vbe of a transitor - Electrical Engineering Stack Exchange
Is VB and VBE, of a transistor the same? If not, how is Vbe generated? and must the base voltage of a transistor be equal to 0 7 or can it exceed this value
- 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
- 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 I add in a resistor to a circuit, the voltage decreases If you have a resistor in a circuit, with a current flowing through it, there will be a voltage dropped across the resistor (as
- voltage - How many amperes can an alkaline AA battery supply . . .
I've seen a Duracell alkaline AA battery on Amazon It can supply 1 5 V, but I don't see any information about the current (in A) or the power (in W) Where can I find this information?
- 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-mode voltage range when designing a circuit, and if so will the op-amp you choose still suffice for your application?
