Continuity of Current: The principle of conservation of charge states that charges can neither be created nor destroyed although equal amounts of positive and negative charge may be simultaneously created, obtained by separation, destroyed or lost by recombination.
Equation 5 indicates that , the current or charge per second, diverging from small volume per
unit volume is equal to the time rate of decrease of charge per unit volume at every point.The velocity is given by,
