## How to convert Electric current in amps (I) to apparent power in volt-amps (VA)?

### amps to VA conversion formula(in Single phase)

The apparent power S in volt-amps (VA) is equal to current I in amps, times the RMS(Root Mean Square) voltage V in volts (V)

**S(VA) = I(in amps) × V(in Volt)**

So that you can define volt-amps(VA) are equivalent to amps times volts(V)

**volt-amps(VA) = amps(I) × volts(V)**

**or**

**VA = A x V**

**Let’s take one example**

**Example#1**

Find out the apparent power in current in the circuit is 10A and voltage supply is 120V in the circuit

Apply formula for the solution:

S = 10A × 120V = 1200VA

### amps to VA calculation formula in 3 phase

**S(VA) = √3 × I(in amps) × VL-L(in Volts)**

So that you can define volt-amps(VA) are equivalent to square root of 3 times amps(I) times volts(V)

**kilovolt-amps(VA) = √3 × amps(I) × volts(V)**

**or**

**kVA = 1.732 × A x V**

**Let’s take one example**

**Example#2**

Find out the the apparent power in VA? where the current is 10A and the voltage supply is 120V in

the circuit?

Apply Formula for the Solution:

S = 1.732 × 10A × 120V = 2078.4 VA
