Question

Assertion (A): In the common domestic circuits, the earth wire is connected to a metallic plate buried deep inside the earth.
Reason (R): Earth wire ensures that any leakage of current to the metallic body of the appliance keeps its potential to that of the earth, so the user may not get a severe electric shock.

• A. Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).
• B. Both Assertion (A) and Reason (R) are true, and Reason (R) is not the correct explanation of Assertion (A).
• C. Assertion (A) is true, but Reason (R) is false.
• D. Assertion (A) is false, but Reason (R) is true.

Hint:

The earth wire provides a safe path for leakage current, reducing the risk of electric shock.

Answer 1

The Correct Option is A

In domestic circuits, the earth wire is indeed connected to a metallic plate buried deep inside the earth to ensure safety. The earth wire provides a path for the leakage current to flow safely into the ground, preventing the metal parts of the appliance from becoming live and thereby protecting users from electric shocks. Thus, both Assertion (A) and Reason (R) are true, and Reason (R) explains Assertion (A).
