Match the following: Column-A Column-B 1) Dry cell (a) converts electricity to heat 2) Oven (b) converts chemicals to electricity 3) Bulb (c) breaks and joins a circuit 4) Switch (d) converts electricity to light.

1-b The source of electric current in a torch is the dry cell. In dry cells chemicals are stored, which reacts and produce electricity. Electric current is the movement or the flow of electrons. 2-a Protons, neutrons and electrons have their own property called the electric charge. In ovens, the electricity is converted into heat energy. This helps to the food to become hot. 3-d Bulb is an example for electrical appliance. The bulb has a glass case mounted on a metallic base. Inside the glass case we can see a thin wire coil called filament. The light bulb are filled with an inert gas such as argon to prevent the filament from reacting with air. 4-c A switch is a device which can break or connect the circuit, so that electric current can flow when required.
