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: Understanding Assertion (A). In domestic circuits, the earth wire is connected to a metallic plate that is buried in the earth to provide a safe path for electric current in case of a fault. 
Step 2: Understanding Reason (R). The earth wire maintains the electrical potential of the appliance at the same level as the earth, ensuring the safety of the user by preventing severe electric shocks. 
Step 3: Conclusion. Since both Assertion (A) and Reason (R) are true, and Reason (R) explains why the earth wire is used, the correct answer is option (A).
