## VA to amps calculator

We are offering the Volt-amps (VA) to amps (A) calculator and help you to calculate. All you need is to enter the value of phase number, voltage in volts, the apparent power in volt-amps, and hit the = button to obtain the current in amps.

## Formula for single phase VA to amps calculation

The value of current I measured in amps is apparently equal to the value of apparent power S in volt-amps, divided by the voltage V in volts.

**I _{(A)} = S_{(VA)} / V_{(V)}**

## Formula for 3 phase kVA to amps calculation

The current I measured in amps is equal to 1000 multiplied by the apparent power S measured in volt-amps, which is divided by the square root of 3 multiplied by the line to line voltage V_{L-L} in volts.

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

#### For Example,

If you need to find the value of current measured in amps and the value of the apparent power is 2000 VA and the voltage supply in volts is 100 volts?

*I* = 2000VA / 100V = 20 A

## Formula for 3 phase VA to amps calculation

The value of current I in amps is apparently equal to the apparent power *S* measured in volt-amps (VA), which divided by the square root of 3 times the line to line voltage *V*_{L-L} measured in volts (V).

**I _{(A)} = S_{(VA)} / (√3 × V_{L-L}_{(V)} )**

So the value of amps is apparently equal to volt-amps which is divided by the square root of 3 multiplied by the volts.

**amps = VA / ( √3 × volts)**

or it can be written as,

**A = VA / ( √3 × V)**

#### For Example,

What is the value of current in amps when the value of apparent power is 4000 VA and the value of voltage supply is 400 volts?

*I* = 4000VA / (*√*3 × 400V) = 10 A
