# Convert VA to Amps (VA to A) Calculation

### VA to Amps Calculator (VA to V):

VA to A calculator is the short form of Volt-Amp to Amp converter. Enter the VA – Apparent Power value to be converted in the first box and enter the voltage in the second box to get the results in ampere.

 Enter phase #: Single phaseThree phase Enter volt-amps: VA Enter line to line volts: V Result in amps: A

Apparent power is only applicable for AC circuit only. In the DC circuit, there is no apparent power term.

### Single Phase VA to Amps Formula:

As we said apparent power is the voltage times of current. hence the current in Amp will be the apparent power divided by the voltage.

I(A) = Current in Amp

V(V) = Voltage in Volts

S(VA) = Apparent Power in VA

Therefore,

I(A) = S(VA) / V(V)

In simple words,

Amp = VA / Volts

### Three Phase VA to Amps Formula:

Three-phase apparent power is equal to three times of single-phase Apparent power while considering Line to neutral voltage. In case while considering line to line voltage, the VA will be the 1.732 times of the single-phase VA.

S(VA) = 3* I(A) * VL-N(V)

Hence, I(A)

I(A) = S(VA) / (√3 × VL-N(V)

While considering Line to line voltage, the formula become

I(A) = S(VA) / (√3 × VL-L(V)

Therefore, the current is equal to apparent power divided by the root 3 times of line to line voltage.

Example:

A generator is delivering 25000 VA at 415V Line to Line, calculate the full load current of the generator.

Apply our formula,

Full load current I(A) = 25000 / (1.732 * 415)

I(A) = 34.78 Amps

### Standard motor VA to Amp (Full load current) conversion chart:

The chart is prepared on the standard motor rating with 0.86 as power factor. The Amps value gives you the full load current calculation of the different rated motor. Also, the full load current can be varied by changing the power factor and voltage.
