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

For safety in household electrical systems, the earth wire connects to a buried metallic plate.This connection provides a safe route for stray current to the ground, preventing appliance metal from becoming energized, thus preventing shocks.Therefore, both the statement (A) and the explanation (R) are correct, with (R) accurately explaining (A).
