current

Current refers to the flow of electric charge through a conductor, such as a wire. It is similar to the flow of water in a pipe, where electricity moves from a source (like a battery or power plant) through various devices to perform work, like lighting a bulb or powering a machine. The amount of current is measured in amperes (amps), indicating how much charge passes through a point in the circuit each second. A higher current means more charge is moving, which can power more devices or produce more energy, depending on the circuit's design.
