Q1. [1] medium exam-ready
Assertion (A): Metallic bodies of electrical appliances such as electric irons and refrigerators are connected to the earth wire.
Reason (R): The earth wire provides a low-resistance path so that any leakage current flows to the earth, keeping the metallic body at earth potential and protecting the user from 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, but 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.
- 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, but 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.

Model Answer
(A)
Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).
Explanation
The textbook (Section 12.4) states exactly that the earth wire provides a low-resistance conducting path, keeps the metallic body at earth potential, and prevents severe electric shock — so R directly and correctly explains A. Choose option (A).
