A constant potential difference is applied between the ends of the wire . If the length of the wire is elongated 4 times , then the drift velocity of electrons will be

A

Increase 4 times

B

Decrease 4 times

C

Increase 2 times

D

Decrease 2 times

Text Solution

Verified by Experts

The correct Answer is:
A
Current in the circuit leads the voltage by `45^circ`
`(1)/(WC) = R+WL`
Rightarrow `C= (1)/W(R+WL)`
`therefore C= (1)(2pi(R+2piFL)`
