VA to Amps Calculator

VA to Amps Calculator

It is used to convert the apparent power in volt-amps (VA) to the current in amps (A). The calculator has both the single phase and three phase. Before you enter the values in their respective cells, it is important to select the phase number to avoid getting mixed results.

Single Phase

If you are using the single phase as your period number, you need to enter the value of the volt amps and the line to line voltage in volts (V) before you click the ‘calculate' button.

Formula for calculating the single phase

I (A) = S (VA) / V (V), which means that the current in amps is calculated by dividing the apparent power S by the voltage V in Volts.

For example;

If the apparent power in volt-amps is 10 VA and tension in line to line volts is 3V, what is the current in Amps?

Solution

I (A) = S (VA) / V (V)
I (A) = 10 / 3 = 3.33
Answer = 3.33 Amps (A)
You can always click the ‘reset' button if you want to perform new calculations.

Three Phase

If you are using the three phase as your phase number, then you need to enter the volt amps and the voltage in line to line volts in their required text fields. After all the cells are filled with the appropriate values, you can click on the ‘Calculate' button to execute the conversion.

Formula for calculating the three phase

I (A) =1000 x S (VA) / (√3 x V L-L (V)) = S (VA) / (3 x V L-N (V)), which means that the current in amps is calculated by multiplying 1000 by the apparent power in volt-amps. The result is the divided by the square root of three multiplied by the line to line voltage in volts.
