Question:

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R

Assertion A: Copper is used to make electrical wires.

Reason R: Copper has very low electrical resistance.

In the light of the above statements, choose the correct answer from the options given below.

Options:

Both A and R are true and R is the correct explanation of A

Both A and R are true but R is NOT the correct explanation of A

A is true but R is false

A is false but R is true

Correct Answer:

Both A and R are true and R is the correct explanation of A

Explanation:
The correct answer is option 1. Both A and R are true and R is the correct explanation of A.
Assertion A: Copper is used to make electrical wires. This statement is true. Copper is a commonly used material for making electrical wires due to its excellent electrical conductivity and other favorable properties.
Reason R: Copper has very low electrical resistance. This statement is true. Copper indeed has very low electrical resistance, which means it allows electricity to flow through it with minimal hindrance. This property makes copper an ideal choice for conducting electricity efficiently.
Therefore, both Assertion A and Reason R are true, and Reason R provides a valid explanation for Assertion A. Copper's low electrical resistance is precisely why it is used for making electrical wires, as it minimizes energy loss during transmission of electricity.
