Question: 1 / 400

If P=IV, what does P stand for?

Voltage

Current

Electric power

In the equation \( P = IV \), \( P \) represents electric power. This relationship indicates that power (in watts) is the product of current (in amperes) and voltage (in volts). Understanding this formula is fundamental in electrical engineering and physics, as it shows how electrical energy is transferred and consumed in a circuit.

Electric power quantifies the rate at which energy is used or generated in an electrical system. The other terms in the equation—current and voltage—are essential to power calculations but do not represent what \( P \) stands for. Current (the flow of electric charge) and voltage (the difference in electric potential) interact to produce electric power, making \( P \) distinctly identifiable as power in this context.
