For the given conductor the drift speed ...

For the given conductor the drift speed of electrons at cross section I, II and III are `v_(d_1)`, `v_(d_2)`, " and `v_(d_3)` , then

A

`v_(d_1) = v_(d_2)=v_(d_3)`

B

`v_(d_1) gt v_(d_2) gt v_(d_3)`

C

`v_(d_1) lt v_(d_2)lt v_(d_3)`

D

`v_(d_1) gt v_(d_2)=v_(d_3)`

Text Solution

Verified by Experts

The correct Answer is:
B
`i="ne"AV_d`
Since current flowing through conductor is same , Hence `AV_d` = constant
`therefore A_1 lt A_2 lt L_3`
`therefore V_(d_1) gt V_(d_2) gt V_(d_3)`
