The existence of electromagnetic waves was first predicted by the scientist .......

To establish an instantaneous displacement current of $I$ ampere in the space between the plates of a parallel plate capacitor of $\frac{1}{2} \text{ F}$,the value of $\frac{dV}{dt}$ is .......

$A$ parallel plate capacitor with a plate separation of $2 \, mm$ is connected to an electric circuit with a source voltage of $400 \, V$. If the plate area is $60 \, cm^2$,what is the value of the displacement current for a time interval of $10^{-6} \, s$?

Who first produced electromagnetic waves?

$A$ parallel plate capacitor of area $A = 16 \ cm^2$ and separation between the plates $10 \ cm$ is charged by a $DC$ current. Consider a hypothetical plane surface of area $A_0 = 3.2 \ cm^2$ inside the capacitor and parallel to the plates. At an instant,the current through the circuit is $6 \ A$. At the same instant,the displacement current through $A_0$ is . . . . . . $mA$.

You are given a $2 \,\mu F$ parallel plate capacitor. How would you establish an instantaneous displacement current of $1 \, mA$ in the space between its plates?
