The formula to calculate Amps (A) from Voltage (V) and Power (W) is:
For DC:
\[ I (\text{A}) = \frac{P (\text{W})}{V (\text{V})} \]
For Single Phase AC:
\[ I (\text{A}) = \frac{P (\text{W})}{V (\text{V}) \times PF} \]
For Three Phase AC:
\[ I (\text{A}) = \frac{P (\text{W})}{V (\text{V}) \times \sqrt{3} \times PF} \]
Where:
Volt (V) is a unit of electric potential, representing the potential difference between two points. Ampere (A) is a unit of electric current, representing the flow of electric charge. The conversion from volts to amps depends on the power and the phase of the circuit.
Let's assume the following values:
Using the formula for Single Phase AC:
\[ I = \frac{1000}{230 \times 1} \]
\[ I = 4.35 \text{ A} \]
The Current (A) is 4.35 A.
