Which formula expresses Watts?

Explanation:
Power in an electrical circuit is the rate at which energy is used. In simple terms, it depends on both the potential difference (voltage) and the amount of current flowing (amps). When you multiply voltage by current, you obtain power, measured in watts. This is written as P = V × I, so Watts equal Volts times Amps. Adding, dividing, or subtracting volts and amps doesn’t represent power, because those operations don’t reflect how energy transfer scales with both voltage and current in a circuit.
