NEET Physics Question - Current Electricity - Relation between Current and Drift Velocity

Assertion (A): Electric field is present in the vicinity of a current carrying wire.

Reason (R): The principle of conservation of charge is not followed, when charges are in motion.

(1) Both (A) & (R) are true and the (R) is the correct explanation of the (A)

(2) Both (A) & (R) are true but the (R) is not the correct explanation of the (A)

(3) (A) is true but (R) is false

(4) Both (A) and (R) are false

Solution:

Assertion (A) is true; an electric field is necessary to drive current through a wire. Reason (R) is false; the principle of conservation of charge is a fundamental law and holds true even when charges are in motion.
