This Presentation is about Domestic Electric Circuits.

1. Domestic
Electric Circuits
Presented by- Yeshwant Rao B
Class- 10 A

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
The excessive flow
of current due to
overuse of
appliances
Short Circuit

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!
