Amps (A) to Volt-amps (VA) calculator and how to calculate
Electric current in amps (A) to apparent power in volt-amps (VA)
In this case, we will be calculating the apparent power S, SI unit volt-amps (VA). The apparent power is calculated by multiplying the RMS voltage V, in volts with the Current I, in amps (A).
S(VA) = I(A) × V(V)
Volt-amps = Volts × amps
VA = A × V
If the current through a circuit is 10A and the Voltage is 110V, what is the apparent power across the circuit?
S = 10A × 110V = 1100VA
Apparent power S (VA), in this case, is equivalent to the line in line RMS VL-L voltage, in volts (V) times the current I, in amps (A) times the square root of 3.
S(VA) = √3 × I(A) × VL-L(V)
Volt-amps is equal to the square root of 3 multiplied by Volts times amps
Volt-amps = √3 × amps × volts
VA = √3 × A × V
Calculate the apparent power, given that the Voltage across a circuit is 110V and the current is 10A
S = √3 × 10A × 110V = 1905VA
