a-4 Dry cell converts chemical energy into electrical energy. It has a positive and a negative terminal. b- 1 The switch can break or connect the electric circuit. It controls the flow of current in the circuit. c- 2 The Filament is a thin wire in the bulb. It gets heated up when a current flows through it and emits light. d- 5 Rubber and plastics are insulators. They will not allow the flow of current through them. Rubber is used in safety gloves and shoes and plastic is used as insulation on wires and in handles of tester as they protect from electric shock. e- 3 Aluminium and copper are conductors. Materials made of metals are common electrical conductors. Column A Column B a. Dry cell 4. Converts chemical energy into electrical energy b. Switch 1. Can break or connect the electric circuit c.

A switch is an electric device that is used to break a circuit or complete a circuit. When a switch is in on position, it will allow the flow of current and when it is in off position, it does not allow the flow of current.
