WAVE EQUATION IN FREE SPACE OR LOSSLESS OR NON-CONDUCTING OR PERFECT DIELECTRIC MEDIUM

WAVE EQUATION IN TERMS OF MAGNETIC FIELD INTENSITY,H

Free space or non-conducting or lossless or in general perfect dielectric medium has following characteristics:

(a)    No condition current i.e σ=0,thus J=0( J=σE)

(b)   No charges (i.e ρ=0)

Therefore for the above cases, Maxwell’s equations will become Continue reading “WAVE EQUATION IN FREE SPACE OR LOSSLESS OR NON-CONDUCTING OR PERFECT DIELECTRIC MEDIUM”

DIFFERENCE BETWEEN DISPLACEMENT CURRENT AND CONDUCTION CURRENT

CONCEPT OF DISPLACEMENT CURRENT (DIFFERENCE BETWEEN DISPLACEMENT CURRENT AND CONDUCTION CURRENT)

Let there be a parallel R-C network with a voltage V as shown in fig .Let the current through resistor R is Ic and by Ohm’s law it is given by

Ic=V/R

And current through capacitor C is Id and is given by Continue reading “DIFFERENCE BETWEEN DISPLACEMENT CURRENT AND CONDUCTION CURRENT”
