Amps to VA Converter:
For converting Amp to Volt-Amp (VA), enter the current in A and voltage in volts, then press calculates button you get the results in Volt-Amps box.
Single-phase Amps to VA calculation:
As you know the apparent power in a circuit is a multiplication of potential difference and the current flow through the circuit. It is denoted by “S”. The unit of apparent power is VA (Volt-Amp).
Hence S = V * I
For single-phase, the voltage to be measured between the line and neutral point.
Three-phase Amps to VA Calculation:
For calculating three-phase current (Amps) to Apparent power, we have two different formula based on the voltage of line to neutral and line to line.
For three-phase current I(A) with a line to neutral voltage,
I(A) = S(VA)/3* V(L-N)
Hence apparent power S in VA is
S(VA) = 3 * I(A) * V(V)
While considering line to line voltage, the Apparent Power S become
S(VA) = √3 * I(A) * VL-L(V)
