Conversion using the VA to Amps Formula

Single Phase VA to Amps Calculation formula

The Current I in amps A is calculated as the Apparent power S in volt-amps, divided by the voltage in Volts V. Plug these values into the formula:

Current(I) = Apparent Power(S) Voltage(V)

or, I(A) = S(VA) V(V)

or, Amps = VA Volts

For Example, let's find the amps for a single-phase electrical circuit with 2400 volt-amps of power at 220 volts.

3-Phase VA to Amps Calculation formula

Calculation with Line to Line voltage

The Current I in amps is Calculated as the Apparent Power S in volt-amps VA, divided by the the square root of 3 times the line-to-line Voltage V_L-L in volt. Plug these values into the formula:

Current(I) = Apparent Power(S) 3 × Voltage(line-line)

or, I(A) = S(VA) 3 × V(L-L)

or, Amps = VA 3 × Volts

For Example, let's find the amps for a 3-phase electrical circuit with 21000 volt-amps of power at 480 volts.

Calculation with Line to Neutal voltage

The Current I in amps is Calculated as the Apparent Power S in volt-amps VA, divided by the the 3 times the line-to-line Voltage V_L-L in volt. Plug these values into the formula:

Current(I) = Apparent Power(S) 3 × Voltage(line-line)

or, I(A) = S(VA) 3 × V(L-L)

or, Amps = VA 3 × Volts

For Example, let's find the amps for a 3-phase electrical circuit with 18000 volt-amps of power at 480 volts.

Frequently Asked Questions - FAQs for VA to Amps Calculator

How to measure VA's apparent power?

Apparent power (VA) is the easiest to measure. it is what you get when you measure the RMS volts with 1 meter and the RMS amps with another meter and multiply the 2.

What is 10 amp power?

Real Power (w) = amps × volts. Thus, a 10 amp socket should theoretically be able to deliver a max of 10 × 220 = 2200 watts.

Why is VA A unit of Real power?

unit of Real Power is a Watt (W). In other terms, we spent one Watt of Power while completing one Joule of Work in one second. 1 Watt = 1 Joule ÷ 1 second.

What is 1500VA in watts?

apparent power (VA) is a rating definition for DC that is V × I. In an AC circuit if your load is pure resistance the same concept will apply what that means is 1500VA is 1500 Watts.

What is apparent power (VA) voltage?

A volt-ampere (VA) is the voltage times the current Flow feeding an electrical load. A kilovolt-ampere (kVA) is 1000 volt-amperes. Electrical Real power is measured in watts (W).
