Question

Assertion (A): In the common domestic circuit, 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 is an essential safety feature in electrical circuits, providing a route for excess current to flow safely into the earth.

Answer 1

The Correct Option is A

Step 1: Assertion (A): In household electrical systems, the earth wire connects to a buried metal plate, providing a safe electrical fault path.
Step 2: Reason (R): The earth wire equalizes appliance potential with earth potential, protecting users from dangerous electric shocks.
Step 3: Conclusion: As both Assertion (A) and Reason (R) are valid, with Reason (R) explaining the purpose of the earth wire, the correct answer is option (A).
