The formula to calculate Amps (A) from Power (W) and Voltage (V) is:
For DC:
\[ I (\text{A}) = \frac{P (\text{W})}{V (\text{V})} \]
For Single Phase AC:
\[ I (\text{A}) = \frac{P (\text{W})}{V (\text{V})} \]
For Three Phase AC:
\[ I (\text{A}) = \frac{P (\text{W})}{V (\text{V}) \times \sqrt{3}} \]
Where:
Watt (W) is a unit of power, representing the rate of energy usage per time unit. Ampere (A) is a unit of electric current, representing the flow of electric charge. The conversion from watts to amps depends on the voltage and the phase of the circuit.
Let's assume the following values:
Using the formula for Single Phase AC:
\[ I = \frac{1000}{230} \]
\[ I = 4.35 \text{ A} \]
The Current (A) is 4.35 A.
