Current is the rate of flow of electrical charge. Use Q = It with charge in coulombs, current in amperes and time in seconds. Electrons carry charge through metals; conventional current is opposite to their net movement. Example: Explain why current is not a store of energy. Current is charge flow per second; electrical work is a transfer mechanism, while energy is held in stores. Rearrange the relationship before substituting if a different quantity is required. Use clear labels. Give a reason.
