Assertion : The connecting wires are made of copper.
Reason : The electrical conductivity of copper is high

A

If both assertion and reason are ture and reason is the correct explanation of assertion.

B

If both assertion and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false.

D

If assertion and reason both are false.

Text Solution

Verified by Experts

The correct Answer is:
A

(a) Due to high electrical conductivity of copper, it conducts the current without offering much resistance. The copper being diamagnetic material does not get magnetised due to current through it and hence does not disturb the current in the circuit.
