If the voltage V applied across a conduc...

If the voltage V applied across a conductor is increased to 2V, how will the drift velocity of the electrons change?

Text Solution

Verified by Experts

The drift velocity, `V_(d) = (eE)/(m) tau = (eV)/(mL) tau`
`(V_(d_(1)))/(V_(d_(2))) = (V_(1))/(V_(2))`
Here `V_(1) = V, V_(2)= 2V`
`(V_(d_(1)))/(V_(d_(2))) = (V)/(2V)`
`:. V_(d_(2)) = 2 V_(d_(1))`
`:.` Drift velocity is increased by twice.
