Aim:
To make a simple switch and show its uses in a circuit.
Materials required:
Small piece of wood or cardboard, two metal thumbtacks, large metal paperclip, three pieces of wire, bulb and bulb holder, battery and battery holder.
Procedure:
1. Insert the battery and bulb into their holders.
2. Connect one wire between the bulb holder and one end of the battery holder.
3. Connect another wire to the other end of the battery.
4. If you are making your own switch, lay the paperclip on the cardboard or wood, push a thumbtack through it, securing it to the board, and push the other thumbtack into the board across from the first so that the paperclip can be rotated to touch both, creating a metal path for electricity to travel.
5. Light the bulb by closing the switch so the electricity can flow through a closed circuit. Turn the bulb off by lifting the switch.
Observations:
When switch is ON - Bulb Light Up, this position is called ON position.
