VA to Amps Conversion Calculator – Convert (VA) to (A)

At 120 Volts, 100 VA = 0.83 A, our va to amps calculator is a powerful tool used to convert volt-amperes (VA) to amperes (A) using I = S / V formula.

VA, or volt-amperes, represents apparent power in an electrical system. It’s the total power supplied to a load, regardless of the power factor. Amps, short for amperes, measure the flow of electric charge through a circuit.

VA to Amps Conversion Formula

The formula to convert VA to amps is:

I = S / V

Where:

• I is the current in amps (A)
• S is the apparent power in volt-amperes (VA)
• V is the voltage in volts (V)

For a 2400 VA load operating at 240 volts:
I = 2400 VA / 240 V = 10 A

A 500 VA device on a 110-volt circuit:
I = 500 VA / 110 V ≈ 4.55 A

How do I convert VA to amps?

Determine the apparent power (S) in volt-amperes (VA).

Identify the operating voltage (V) of the system or device.

Apply the conversion formula: I = S / V

Calculate the result to obtain the current in amps.

Let’s convert 3000 VA to amps for a 220-volt system:

Apparent power (S) = 3000 VA

Operating voltage (V) = 220 V

Apply the formula: I = 3000 VA / 220 V

Calculate: I = 13.64 A

A 3000 VA load on a 220-volt system draws approximately 13.64 amps.

• For three-phase systems, divide the result by √3 (square root of 3).
• Power factor affects the relationship between apparent power (VA) and real power (watts). In systems with a power factor less than 1, the current draw will be higher than calculated using only VA.

How many amps is a 50 VA transformer?

Consider a 50 VA transformer with both 12V and 24V taps:

For the 12V tap:

I = 50 VA / 12 V = 4.17 A

This means the 12V winding can supply up to 4.17 amps.

For the 24V tap:

I = 50 VA / 24 V = 2.08 A

The 24V winding can provide up to 2.08 amps.

Scenario 1: 12V output
Using the formula I = S / V:
I = 50 VA / 12 V ≈ 4.17 A

Scenario 2: 24V output
I = 50 VA / 24 V ≈ 2.08 A
