Amps (A) to volt-amps (VA) calculator and how to calculate or how to use it.

Enter phase number, the current in amps, the voltage in voltsand press the *Calculate* button,

to get the apparent power in volt-amps:

The apparent power S in volt-amps is equal to current I in amps, times the voltage V in volts:

*S*_{(VA)} = *I*_{(A)} × *V*_{(V)}

The apparent power S in kilovolt-amps is equal to square root if 3 current I in amps, times the line to line voltage V_{L-L} in volts:

*S*_{(VA)} = *√*3 × *I*_{(A)} × *V*_{L-L(V)} = 3 × *I*_{(A)} × *V*_{L-N(V)}
