ELECTRICITY
1.Definition: Electric current is the flow of electric charge through a conductor, such as a metallic wire.
2.Analogy: Just as water current refers to the flow of water in a river, electric current refers to the flow of electric charges in a circuit.
1.Source of Electric Current: In devices like a torch, cells or batteries provide the electric current necessary for operation.
2.Conducting Path: The current flows through a continuous and closed path, which is known as an electric circuit.
3.Switch: A switch is a device that can either complete (turn on) or break (turn off) the circuit, thereby controlling the flow of current. When the switch is on, it creates a conducting link between the power source and the load (e.g., a bulb).
