The voltage between the plates of a parallel plate capacitor of capacity $1 \ \mu F$ is changing at the rate of $4 \ V/s$. The displacement current in the capacitor is: (in $\mu A$)

When a displacement current $i_d$ flows in the region between the two plates of a capacitor,the charge on the capacitor is:

According to Maxwell,a changing electric field produces .......

The existence of electromagnetic waves was experimentally confirmed by

Electromagnetic waves are produced by

An alternating voltage of amplitude $40 \, V$ and frequency $4 \, kHz$ is applied directly across a capacitor of $12 \, \mu F$. The maximum displacement current between the plates of the capacitor is nearly: (in $ \, A$)
