Q. A steady current $i$ is flowing through a conductor of uniform cross-section. Any segment of the conductor has
A) Zero charge
B) Only positive charge
C) Only negative charge
D) Charge proportional to current $i$
Explanation
(a) As steady current is flowing through the conductor, hence the number of electrons entering from one end and outgoing from the other end of any segment is equal. Hence charge will be zero
