A) current density
B) current
C) drift velocity
D) electric field
Correct Answer: B
Solution :
As the cross-sectional area of the conductor is non-uniform so current density will be different. As \[I=JA\] ?(i) It is clear from Eq. (i), when area increases the current density decreases so the number of flow of electrons will be same and thus the current will be constant.You need to login to perform this action.
