hello everyone i would like to know why charge density and current density in free space are zero??????????
@pratap singh, upendra • 24 May, 2012
actual charge density and current density is not zero in free space.
However, when we talk about charge density or current density we more often than not talk about their average values which are of course zero, on account of random motion of charges in one form or the other. These charges behave as a gas molecules that can occupy any position and move in any direction.
when the effect of all charges present in free space is taken together, the resultant is always zero

Free sace is essentially one hydrgen atom er cubic kilometer. Charges do not exist in isolation. There has to be elctrons or positive ions. Free space has neither.ankush chaudharyhello everyone i would like to know why charge density and current density in free space are zero??????????
