Electric current in circuits is the rate of charge flow indicated by arrows in circuit diagrams. The flow of electrons from positive to negative terminals defines the direction of current. Understanding how current flows through a circuit is crucial in analyzing electrical systems.
Electric current is the rate of charge flow in a closed circuit. In a circuit diagram, it is represented by arrows indicating the direction of flow, typically from the positive terminal to the negative terminal of a battery.
For example, in a simple circuit containing a battery, a switch, wires, and a lamp, the current flows from the positive terminal of the battery, through the components, and back to the negative terminal.
This flow of electrons constitutes the electric current in a circuit, following the complete path guided by the closed circuit.
