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 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"?
6 It's not the voltage but the current that kills, is a popular yet still incorrect incomplete answer. It is the ENERGY that kills. With static electricity you will will be exposed to voltages much, …
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 …
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.
voltage - Vb and Vbe of a transitor - Electrical Engineering Stack …
Sep 23, 2023 · 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.
voltage - Why does a voltmeter read lower across a load than …
The reason why there is always a voltage drop in an electric circuit without giving consideration to the internal resistance of the battery or the voltage source is the resistance in the wires used in …
Why does voltage drop in a series circuit but current stays the …
May 23, 2021 · 3 Understanding voltage will clear your confusion as to why voltage drops in series circuits and currents stays the same. Hence I will try to explain to voltage (electric …
Reducing voltage with resistors - Electrical Engineering Stack …
Sep 2, 2014 · As others have mentioned you can use a voltage divider of two resistors, but the voltage divider output will change if the load current changes. You can still use a voltage …
Why does voltage drop across resistance contradict Ohm's law?
Aug 10, 2020 · Here when current flows in this circuit, due to ohm's some voltage has to be dropped across the internal resistance r, causing the output voltage, i.e, the voltage available …
