Continuity Equation (in Electricity)

The continuity equation in electricity states that electric charge cannot be created or destroyed within a closed system. This means that the amount of charge flowing into a point must equal the amount flowing out over time. In practical terms, if a current flows through a wire, the total charge passing a point per second remains constant, assuming no charge is added or lost. This principle ensures the conservation of charge, maintaining a steady flow and allowing us to understand and predict electrical behavior in circuits and systems accurately.
