## How to convert apparent power in kilovolt-amps (kVA) to electric current in amps (A)?

### kVA to amps calculation formula in case of Single phase

I=The phase current I in amps
S=the apparent power S in kilovolt-amps
V=the Root Mean Square voltage V in volts
I(A) = 1000 × S(in kVA) / V(in Volts)
So that you can define Cuurent(I) in amps are equal to 1000 times KVA divided by Voltage(V).
amps(A) = 1000 × kVA / volts(V)
or you can re-write this formula like that
A = 1000 x kVA / V
Let's take an example
Example#1
We need to find out the current(I) in amps of an electric circuit where power(S) is 5 kVA and root mean square voltage in the circuit is 100 volts
Apply formula for the Solution:
I = 1000 × 5kVA / 100V = 50A

### kVA to amps calculation formula in case of 3 phase with line to line voltage

I=The phase current I in amps
S= the apparent power S in kilovolt-amps
VL-L= the line to line Root Mean Square voltage V in volts
I(A) = 1000 × S(in kVA) / (1.732 × VL-L(in Volts) )
So that you can define cuurent(I) in amps are equal to 1000 times KVa divided by the 1.732 times volts(V).
amps = 1000 × kVA / (1.732 × volts)
Let's take an example
Example#2
We need to find out the current(I) in amps of an electric circuit where the power(S) is 5 kVA  and the line to line root mean square voltage supply is 150 volts in the circuit.
Apply formula for the Solution:
I = 1000 × 5kVA / (1.732 × 150V) = 19.236A

### kVA to amps calculation formula in case of 3 phase with line to neutral voltage

I=The phase current I in amps
S=the apparent power S in kilovolt-amps
VL-Nthe line to line RMS voltage V in volts
I(A) = 1000 × S(in kVA) / (3 × VL-N(in Volts) )
So that you can define Current(I) in amps are equal to 1000 times Power in KVA divided by 3 times voltage.
amps(A) = 1000 × kVA / (3 × volts(V))
or
A = 1000 x kVA / (3 × V)
Let's take an example
Example#3
We need to find out the current(I) in amps of an electric circuit where the power(S) is 5 kVA  and the line to neutral root mean square voltage supply is 150 volts in the circuit.
Apply formula for the Solution:
I = 1000 × 5kVA / (3*150V) = 1.11A
