1. Domestic Electric Circuits Presented by- Harmanjeet Singh Class- 10

2. How is electricity generated?

3. Power Plant Generator Mechanical Energy Electrical Energy

4. Electrical energy reaches our homes via wires coming from the poles Electrical Energy reaching home

5. These wires are called Mains

6. Live wire or Positive Wire Neutral wire or Negative wire

7. The potential difference between the live and the neutral wire in India is 220V

8. Wires in domestic circuits

9. Colour Coding

10. What is the use of Ground wire? V= 0 for ground with very low resistance

11. Mains have two circuits Lightning Circuits 5A for low power consumption devices Power Circuits 15A for high power consumption devices

12. Hazards of Domestic Circuits Overloading Short Circuit The excessive flow of current due to overuse of appliances

13. Hazards of Domestic Circuits Overloading The excessive flow of current due to overuse of appliances Short Circuit Flow of High current in the circuit when live and neutral wires come in direct contact

14. How do we prevent overloading and short circuit? We use Fuse and MCB’s

15. THANK YOU!
