Question

Assertion (A): A current flows in a conductor, only when there is an electric field in the conductor
Reason (R): The drift speed of an electron in presence of electric field decreases.
a) Both A and R are true and R is the correct explanation of A
b) Both A and R are true and R is the not correct explanation of A
c) A is true. Ris false
d) A is false, R is true​

Answer 1

Current flows when there in P.D.

The presence of P.D implies the presence of Electric field.

Drift velocity ∝ Electric field.
