Electrical current

Definition

Electrical current refers to the flow of electric charge (usually electrons) through a conductor or circuit. It is measured in amperes (A).

Analogy

Imagine water flowing through pipes. The rate at which water flows represents electrical current, while the pipes act as conductors. The more water flowing, the higher the current.

Voltage: Voltage is the electrical potential difference between two points in a circuit, which causes current to flow. It is measured in volts (V).

Resistance: Resistance is a property of a material that opposes the flow of electric current. It determines how much current can pass through a component for a given voltage.

Power: Power is the rate at which work is done or energy is transferred in an electrical circuit. It is calculated by multiplying voltage and current, and it is measured in watts (W).
