Question

a conductor of length L is connected to a dc source of emf E. If ts conductor is replaced by another conductor of same material and same area of cross section but length 3L, how will the drift velocity change ?

if helpful mark as brainest answer........

Answer 2

The drift velocity will become 1/3rd of original velocity.

Given - Length

Find - New drift velocity

Solution - The drift velocity and length are directly proportional to each other.

V1/V2 = l2/l1

Keep the values in formula

V1/V2 = 3L/L

Cancelling L on RHS

V1/V2 = 3/1

V2 = V1/3

Hence, the drift velocity be 1/3rd of the original drift velocity.
