Solution

Verified by Toppr

The quantity of charge passing through any cross-section per second is nothing but current flowing in the conductor.
As given, the current is steady current, means current is uniform throughout the cross-section. Hence it is independent of Area of cross section.

Q4

We know that current

I = n e A V_{d}

where

V_{d}

is the drift speed, A is the cross sectional area, e is the magnitude of charge on an electron and n is the number of free charge carriers in unit volume of a conductor. In a conductor of non-uniform cross-sectional area as shown

1: The current at P will be more than the current at Q
2: Because current is directly proportional to cross-sectional area so current increases as the cross sectional area increases

Q5

Assertion :Consider a current carrying wire whose cross section area decreases gradually along the direction of current, like as shown in figure. As one goes from cross-section

A

to cross-section

B

, the drift speed of electron increases. Reason: Electric field intensity at any cross-section in a current carrying wire is in inversely proportional to its cross sectional area.
