The electric torch 35 The purpose of this device is to produce a small beam of light. You can use it outside at night, or if the electricity in your house is not working. 36 The device has a body, a bulb, a lens, a reflector, a switch and batteries. 37 The body is made of metal. The lens is made of glass or plastic. 38 Electric torches are usually between 20 and 35 cm long, and 5 to 10 cm in width. 39 The job of the batteries is to provide electrical current for the bulb. The purpose of the bulb is to convert electrical current into a source of light. The reflector changes the light from the bulb into a single beam. The job of the lens is to focus the light beam into a single point of light. The switch opens and closes the circuit from the batteries to the bulb. 40 The batteries are inside the body, the lens is attached to the front of the reflector, the bulb is behind the lens and the switch is mounted on the outside of the body. 41 If you want to switch it on, simply slide the switch forwards. If you want to switch it off, slide the switch backwards. 42 When you slide the switch forwards, the circuit is closed. The electric current flows from the batteries into the bulb, and the bulb lights up.
