What does electric current measure?

Electric current measures the flow of electrical charge in a circuit. It represents how much electrical energy is moving through a circuit at a given point in time. It is typically measured in amperes (A).

The amount of electrical energy that moves in a circuit is determined by the current flowing through it and the amount of time it flows for. This is typically measured in watt-hours (Wh) or joules.

The speed at which electrical energy moves in a circuit is represented by the current. A higher current means a faster flow of electrical energy.

The frequency at which electrical energy moves in a circuit can vary depending on the specific circuit and the components involved. In alternating current (AC) circuits, the direction of the current changes periodically, typically at a frequency of 50 or 60 hertz (Hz). In direct current (DC) circuits, the current flows steadily in one direction without changing.

Overall, electric current measures the flow of electrical energy in a circuit, representing both the amount and speed of that flow.
