define volume charge density
Answers
Answer: In electromagnetism, charge density is the amount of electric charge per unit length, surface area, or volume. Volume charge density (symbolized by the Greek letter ρ) is the quantity of charge per unit volume, measured in the SI system in coulombs per cubic meter (C⋅m−3), at any point in a volume.
Hope it helps.........
Answer:
when we are asked about volume charge density ,then we must have to know about the system configuration at first .i.e.in the case of microscopic physics , we can neglect the quantized - nature of the electric charge and considere it as a continous system. In a microscopic charge distribution even a small volume elements contain large number of elementary charges. In such a situation, the concept of charge densities take an entry simply just by avoiding impractical counts of individual charges.
