Solution

The correct option is C
An we move from A to B, firstly area decreases and then increases. Since $j = \frac{i}{A}$ , firstly j increases and then decreases.
SInce $j = σ E, E$ follows same pattern as of j.

An electric current flows along conductor AB as shown in figure. →E in conductor AB varies as

The correct option is C An we move from A to B, firstly area decreases and then increases. Since j=iA, firstly j increases and then decreases. SInce j=σE,E follows same pattern as of j.
