Amps to VA

Amps (A) to Volt-amps (VA) converter

Amps to VA conversion

Electric current in amps (A) to apparent power in volt-amps (VA)

Single phase amps to VA conversion

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)

Therefore:

Volt-amps = Volts × amps

Or

VA = A × V

Example

If the current through a circuit is 10A and the Voltage is 110V, what is the apparent power across the circuit?

Solution

S = 10A × 110V = 1100VA

3 phase amps to VA conversion

Apparent power S (VA), in this case, is equivalent to the line in line RMS V_L-L voltage, in volts (V) times the current I, in amps (A) times the square root of 3.

S_(VA) = √3 × I_(A) × V_L-L(V)

Therefore:

Volt-amps is equal to the square root of 3 multiplied by Volts times amps

Volt-amps = √3 × amps × volts

Or

VA = √3 × A × V

Example

Calculate the apparent power, given that the Voltage across a circuit is 110V and the current is 10A

Solution:

S = √3 × 10A × 110V = 1905VA
