Assertion : Electrons which constitute the current arc negatively charged.
Reason: Current carrying wire is negatively charged.

A

If both assertion and reason are true and reason is the correct explantion of assertion.

B

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

C

If assertion is false but reason is true.

D

If assertion is true but reason is false.

Text Solution

Verified by Experts

The correct Answer is:
C
Electrons that constitute current are negatively charged. A wire carrying current is not charged. Inside the wire the number of electrons equals to the number of protons, at any instant. Therefore the conductor is neutral. The current in the conductor is due to the flow of electrons from the negative terminal to the positive terminal.
