Question 2

State how these precautions prevent possible damage to the electric circuit.

Accepted Answer

1. **Earthing** provides a low-resistance path for leakage current to flow safely into the ground, preventing severe electric shock to the user. 2. **Fuse** melts and breaks the circuit when current exceeds safety limits due to overloading or short-circuiting, protecting appliances from damage.
