Understanding Volume Charge Density

Volume charge density ($\rho_q$) represents charge per unit volume ($\rho_q = \frac{Q}{V}$), measured in coulombs per cubic meter ($\text{C}/\text{m}^3$). Forms the source term in Gauss's law of electrostatics ($\nabla \cdot \vec{E} = \frac{\rho_q}{\epsilon_0}$) and space-charge modeling in vacuum tubes and ionized plasmas.
