In electromagnetic theory, continuity equation relates _______ Correct Answer Charge conservation

In electromagnetic theory, charge conservation is a result of Maxwell’s equation which states that divergence of current density is equal to the negative rate of change of charge density. ∇.J=- ρ/t Where J-current density and ρ-charge density.
