1.	A plane electromagnetic wave of frequency `v=10 MHz` propagates in a poorly conducting medium with conductivity `sigma=10 mS//m` and permittivity `epsilon=9`. Find the ratio of amplitudes of conduction and displacement current densities.
Answer» Conduction current density `= sigmavec(E)` Displacement current density `=(deltavec(D))/( deltat)=epsilonepsilon_(0)(deltavec(E))/( delta t ) = i omega epsilon epsilon_(0)vec(E)` Ration of magnitudes `=( sigma)/( omega epsilon epsilon_(0))=(j_(c))/( j_(dis))=2`, on putting the values.
