How to convert volt-amps to amps?

va to amps converter formula

Apparent power in volt-amps (VA) to electric current in amps (A).
VA to amps calculation formula in case of Single phase
I=The current I in amps
S=the apparent power S in volt-amps (VA)
V=the Root Mean Square voltage V in volts (V)
I(in Amps) = S(VA) / V(in Volts)
So that you define Current(I) in amps are equal to VA divided by volts(V)
amps(A) = VA / volts(V)
or you can re-write formula like this
A = VA / V
Let's take an example
Example#1
Find out the Phase current in amps?where the apparent power(S) is 2000 VA and the voltage(V) supply is 100 volts in the circuit.
Apply formula for the Solution:
I = 2000VA / 100V = 20A

VA to amps calculation formula in case of 3 phase

I=The current I in amps
S=the apparent power S in volt-amps (VA)
VL-L=the line to line voltage VL-L in volts (V)
I(in Amps) = S(VA) / (1.732 × VL-L(in Volts) )
So that you can define Current(I) in amps are equal to VA divided by
the 1.732 times volts(V).
amps = VA / (1.732 × volts)
or you can re-write this formula like that
A = VA / (√3 × V)
Let's take an example
Example#2
Find out the phase current(I) in amps where the apparent power(s) is 2000 VA and the voltage(V) supply is 100 volts in the circuit.
Apply formula for the Solution:
I = 2000VA / (1.732 × 100V) = 11.54A
