The formula to calculate Amps (A) from Volt-Amps (VA) and Voltage (V) is:
For Single Phase:
\[ I (\text{A}) = \frac{S (\text{VA})}{V (\text{V})} \]
For Three Phase:
\[ I (\text{A}) = \frac{S (\text{VA})}{V (\text{V}) \times \sqrt{3}} \]
Where:
VA (volt-amps) is a unit of apparent power, representing the total power in an electrical circuit. Amps (A) is a unit of electric current, representing the flow of electric charge. The conversion from VA to amps depends on the voltage and the phase of the circuit.
Let's assume the following values:
Using the formula for Single Phase:
\[ I = \frac{1000}{230} \]
\[ I = 4.35 \text{ A} \]
The Current (A) is 4.35 A.
