## How to convert VA to amps

Apparent power in volt-amps (VA) to electric current in amps (A).

You can calculate amps from volt-amps and volts, but you can't convert volt-amps to amps since volt-amps and amps units do not measure the same quantity.

## Single phase VA to amps calculation formula

The current I in amps is equal to the apparent power

Sin volt-amps (VA), divided by the RMS voltageVin volts (V):

I_{(A)}=S_{(VA)}/V_{(V)}So amps are equal to volt-amps divided by volts.

amps = VA / volts

or

A = VA / V

## Example

Question: What is the current in amps when the apparent power is 3000 VA and the voltage supply is 110 volts?

Solution:

I= 3000VA / 110V = 27.27A## 3 phase VA to amps calculation formula

The current I in amps is equal to the apparent power

Sin volt-amps (VA), divided by the square root of 3 times the line to line voltageV_{L-L}in volts (V):

I_{(A)}=S_{(VA)}/ (√3 ×V_{L-L}_{(V)})So amps are equal to volt-amps divided by the square root of 3 times volts.

amps = VA / (

√3 × volts)or

A = VA / (

√3 × V)## Example

Question: What is the current in amps when the apparent power is 3000 VA and the voltage supply is 110 volts?

Solution:

I= 3000VA / (√3 × 110V) = 15.746A
