- 3. Switch A switch is a simple device that either breaks the circuit or completes it.
- 4. Material CONDUCTOR • Materials that allow electric current to pass through them are called conductors. INSULATOR • Materials that do not allow electric current to pass through them are called insulators.
- 5. List of material CONDUCTOR • Sewing needle, keys, pins, coins and metals etc. INSULATOR • Cork, rubber, glass, plastic scale, wooden block, candle, thermo Col, paper and pencil lead and Non metals etc.
Editor's Notes
- Hello Students ,in this part we will cover about switch. So when the switch is on, Torch bulb gives light The switch is not only the part of torch
- but we see switches everyday all around us, for example in our study room, dining room or main switch board etc
- A switch is a simple device that either breaks the circuit or completes it. So till here we have completed about the torch and its components,
- Now we will understand about the material used in electricity and circuit Basically we use two type of material conductor and insulator Materials that allow electric current to pass through them are called conductors. Where as Materials that do not allow electric current to pass through them are called insulators.
- Conductors are Sewing needle, keys, pins, coins and metals etc. Whereas insulators are Cork, rubber, glass, plastic scale, wooden block, candle, thermo Col, paper and pencil lead and Non metals etc. So here our chapter-12 completed. For the next chapter click on Chapter-13 Fun with magnet
