Question

The electric field in the region between two parallel plates is shown below. The displacement current in the region is $i_d$. Then -

• A. $i_d=0$
• B. $i_d=\infty$
• C. $i_d>0$
• D. $i_d<0$

Answer 1

The correct option is A $i_d=0$


From the above diagram, we can conclude that, electric field is uniform through the given region.

Therefore, electric flux is constant.

So, $\frac{d{\varphi }_E}{dt}=0\Rightarrow i_d=0$

Hence, option $\left(A\right)$ is the correct answer.
