Without the help of insulators, the use of electrical tools like pliers and screwdrivers will give electric shock to user. Wood and plastics are insulators and help in avoiding direct contact with electric current. When electricians touch these live electric wires with these tools covered with plastic or rubber, current does not flow in their body making safer them from any accident.
Electricians frequently touch copper wires or they may accidentally come in contact with live wires (wires carrying current). Since human body is a good conductor, electricians may get shock. Rubber is an insulator. To prevent themselves from electric shock or flow of current, the electricians use rRead more

Since the object allows current to flow and completes the circuit and makes bulb to glow. It means the object is a conductor of electricity. https://www.tiwariacademy.com/ncert-solutions/class-6/science/chapter-12/

A switch is a simple device that either breaks the circuit or completes it. The switches used in lighting of electric bulbs and other devices in homes work on the same principle. In radio, TV, mobiles, torch and electric toys have in built switches. https://www.tiwariacademy.com/ncert-solutions/clasRead more
