Volt-Amps (VA) to Amps Formulas
Calculate current from apparent power in electrical systems
Single Phase Calculation
The current I in amps is equal to the apparent power S in volt-amps divided by the voltage V in volts:
I(A) = S(VA) / V(V)
Where:
- I(A) Current in Amperes (A)
- S(VA) Apparent power in Volt-Amps (VA)
- V(V) Voltage in Volts (V)
Three Phase Calculation
Calculation with Line to Line Voltage
I(A) = S(VA) / (โ3 ร VL-L(V))
Where:
- I(A) Current in Amperes (A)
- S(VA) Apparent power in Volt-Amps (VA)
- VL-L Line to line voltage (V)
Calculation with Line to Neutral Voltage
I(A) = S(VA) / (3 ร VL-N(V))
Where:
- I(A) Current in Amperes (A)
- S(VA) Apparent power in Volt-Amps (VA)
- VL-N Line to neutral voltage (V)
Practical Example
Single Phase Example
Given:
- Apparent Power (S) = 2300 VA
- Voltage (V) = 230 V
Calculation:
I(A) = 2300 VA / 230 V = 10.00 ANote: Results are typically rounded to two decimal places for practical applications. Always consider the specific requirements of your application for appropriate precision.
