Electrical Power

Definition

Electrical power refers to the rate at which electrical energy is transferred or consumed in a circuit. It is measured in watts (W) and can be calculated by multiplying the voltage (V) across a device by the current (I) flowing through it.

Analogy

Think of electrical power as the speed at which water flows through a pipe. The wider the pipe (higher voltage), and the stronger the water pressure (higher current), the more power is being transferred.

Voltage: Voltage, also known as electric potential difference, is the force that pushes electric charges through a circuit. It is measured in volts (V).

Current: Current refers to the flow of electric charge in a circuit. It is measured in amperes (A).

Resistance: Resistance is an opposition to the flow of electric current. It determines how much current will flow for a given voltage. It is measured in ohms (Ω).
