Electric current is the movement or flow of electric charges through a conductor. It is denoted by the symbol 'I' and can be calculated using the formula I = Q/t, where 'Q' represents the charge in coulombs, and 't' represents time in seconds. One ampere (1 A) of current indicates a flow of one coulomb per second. Understanding electric current is essential for grasping fundamental electrical concepts, as it directly impacts the functioning of electrical devices and systems.
