Question 2
Match the column
 Column A Column B Covering of switches, appliances, plugs socket is made of insulator It is a simple device that either breaks the circuit or completes it. When the terminals of the bulb are connected with that of the electric cell by wires because it does not allow current to pass through them so we do not get shock if we touch them electric switch The current passes through the filament of the bulb. This makes the bulb glow. An electrician use rubber gloves while repairing an electric switch at your home is a device which converts chemical energy into electric energy. electric cell Because it is an insulator and it prevent electric shock
