For the Assertion A and Reason R given below choose the correct alternative from the following
A : Copper is used to make electric wire
R : Copper has very low electric resistance
A : Copper is used to make electric wire
R : Copper has very low electric resistance
- Both A and R are true and R is the correct explanation of A
- Both A and R are true and R is not the correct explanation of A
- A is true, R is false
- A is false, R is true
The Correct Option is A
Solution and Explanation
To analyze the given assertion (A) and reason (R), we need to understand their meanings and how each relates to the other:
Assertion (A): Copper is used to make electric wires.
Reason (R): Copper has very low electric resistance.
Let's evaluate both statements:
-
Truth of Assertion (A): Copper is indeed widely used in the manufacturing of electrical wires. This is a factual statement as copper is a common choice for electrical wiring due to its excellent electrical conductivity.
-
Truth of Reason (R): Copper indeed has very low electrical resistance which facilitates the efficient flow of electric current. This property makes it highly suitable for use in electrical applications.
Explanation: The reason provided (R) directly explains why copper is used for electrical wires. The low electrical resistance of copper means that it can conduct electricity with minimal energy loss. In turn, this minimizes power loss over the length of the wire and increases its efficiency for electrical wiring applications, making R the correct explanation for A.
Thus, both statements are true, and R is the correct explanation of A.
Conclusion: The correct answer is: Both A and R are true and R is the correct explanation of A.
