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 force") …
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 is usually much …
Why did current increase when voltage decreased?
Jan 6, 2024 · At a lower voltage, you need more current to provide the same power. So any device that is designed to provide the same power regardless of voltage will draw more current as the voltage …
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.
Reducing voltage with resistors - Electrical Engineering Stack Exchange
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 divider and fix this …
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 …
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, much, much …
Difference between voltage and phase angle - Electrical Engineering ...
May 23, 2023 · 0 The voltage at a node can be described by $$ V = |V|e^ {j \delta} $$ in which \$\delta\$ is the voltage angle. Voltage angles are required to calculate AC power flows. The phase angle if …
Difference between Working Voltage and Isolation Voltage?
Feb 12, 2022 · The isolation voltage is just the rated maximum between two galvanic systems that are supposed to remain isolated. Just think of it as insulation, like what surrounds an insulated wire. That …
voltage - Is power proportional to V or V^2? - Electrical Engineering ...
Jan 20, 2021 · Yes, because I is a function of V, as long as we're talking about resistors. Power is linearly proportional to voltage, though, if you're talking about a constant current device.
