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 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 - "Ground" vs. "Earth" vs. common vs. negative terminal ...
Aug 4, 2014 · Voltage has exactly the same problem: one terminal can only "have a voltage" when compared to another terminal. Voltage acts like distance: voltage and distance are …
voltage - What is the difference between Vrms and Vm? - Electrical ...
Apr 8, 2013 · I am relatively new here and I am confused as to the difference between Vrms and Vm. I would be obliged if someone can explain. (This in relation to 3-phase circuits would be …
How much voltage/current is "dangerous"?
Likewise, if the current and voltage are below a certain level, a person can--given enough time--safely absorb an arbitrarily large amount of electrical energy. Further, if voltage is sufficiently …
voltage - How does data travel inside a wire? - Electrical …
Current and voltage are inseperable. The current is flowing because there is a voltage on the wire, and there is a conductive path from that voltage to a lower voltage. So we can say the data is …
Why does the USA use 110V and UK use 230-240V?
Jun 14, 2014 · USA uses 230-240 VAC, too. The only difference is that we ground it in the center, creating "split" phases, reducing the peak voltage relative to ground and making it easier to …
voltage - Explain in layman's terms Vgs and Vgs (th) of MOSFET's ...
Feb 26, 2015 · Vgs (th) is the voltage at which the mosfet channel begins to conduct. At this voltage, a positive voltage, it creates an electric field, which attract electrons (since our applied …
voltage - Minimum clearance between two traces that have a …
Aug 30, 2017 · I am designing a PCB and there will be high voltages. What is the recommended clearance that I should have between two traces that have a voltage difference of 1000VDC …
What exactly does "common-mode" mean in the context of op …
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 …
