Since watts is volts times amps, what is VA? VA (or volt-amps) is also volts times amps, ... So in AC, if the volts and amps are not precisely in phase you have to calculate the watts by multiplying the volts times the amps at each moment in time and take the average over time. The ratio between the VA (i.e. rms volts time...

The unit of resistance is called Ohm in honor of a German scientice by the name of Georg Simon Ohm, who discovered that when a conductor has a resistance of 1 ohm than an emf of 1 volt will cause a current of 1 amp to flow through a conductor. ... Enter two known values and press Solve to calculate unknowns.

Volt-ampere (VA) is a measurement of power in a direct current (DC) electrical circuit. The VA specification is also used in alternating current (AC) circuits, but it is less precise in this application, because it represents apparent power, which often d ... volt-ampere Activate your FREE membership today | Log-in...
