Match the following: Column A Column B 1) Cell A) Conductor 2) Switch B) Source of electricity 3) Safety pin C) Filament 4) Eraser D) To close or open a circuit 5) Glowing of bulb E) Insulator

A cell is an important component in the circuit. The current flows only when a cell is present in any circuit. Two or more cells combine to form a battery and it also produces electricity. A switch is an electrical component that can disconnect or connect the conducting path in an electrical circuit, interrupting the electric current or diverting it from one conductor to another. It can be in ON or OFF state Conductors are the materials or substances which allow electricity to flow through them. They are also known as good conductors of electricity. For the bulb to glow in an electric circuit , conducting materials has to be used. Metal like a safety pin is an example of a conductor. Insulators are the materials or substances which resist or do not allow the current to flow through them. They are solid in nature and are poor conductors. An eraser is an example of an insulator. Bulbs use heat to glow. When electrical current passes through a wire or filament it gets heated, and the bulb starts glowing. Also, the circuit should be a closed one for the bulb to glow.
