The electric field through an area of $2 \ m^2$ varies with time as shown in the graph. The greatest displacement current through the area is at $t = ..... \ \mu s$.

Which scientist experimentally proved the existence of electromagnetic waves?

An infinitely long thin wire carrying a uniform linear static charge density $\lambda$ is placed along the $z-$axis. The wire is set into motion along its length with a uniform velocity $\vec{V} = v\hat{k}$. Calculate the Poynting vector $\vec{S} = \frac{1}{\mu_0}(\vec{E} \times \vec{B})$.

The displacement current through the plates of a parallel plate capacitor of capacitance $30 \mu F$ is $150 \mu A$. The capacitor is charged by a source of varying potential at the rate of: (in $Vs^{-1}$)

In the charging of a capacitor,what is the contradiction in Ampere's circuital law?

$A$ parallel plate capacitor with circular plates of radius $R$ is being charged as shown. At the instant shown,the displacement current in the region between the plates enclosed between $\frac{R}{2}$ and $R$ is given by
