A conducting wire of cross-sectional area 
has 
charge carriers per 
. If wire carries a current 24 mA , then drift velocity of carriers is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
The current I crossing area of cross-section A, can be expressed in terms of drift velocity v d and the moving charges as
where, n is number of charge carriers per unit volume and e the charge on the carrier.
