The formula to calculate Amps (A) or Volts (V) from Power (W) is:
For DC:
\[ I (\text{A}) = \frac{P (\text{W})}{V (\text{V})} \]
\[ V (\text{V}) = \frac{P (\text{W})}{I (\text{A})} \]
For Single Phase AC:
\[ I (\text{A}) = \frac{P (\text{W})}{V (\text{V})} \]
\[ V (\text{V}) = \frac{P (\text{W})}{I (\text{A})} \]
For Three Phase AC:
\[ I (\text{A}) = \frac{P (\text{W})}{V (\text{V}) \times \sqrt{3}} \]
\[ V (\text{V}) = \frac{P (\text{W})}{I (\text{A}) \times \sqrt{3}} \]
Where:
Watt (W) is a unit of power, representing the rate of energy usage per time unit. 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 between these units depends on the power, voltage, and current in 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.
