Conventional current is the flow of positive charge from the positive to the negative terminal of a power source, which is opposite to the actual flow of electrons in a circuit. This concept is a historical convention that simplifies circuit analysis and is widely used in electrical engineering and physics despite the electron flow being in the opposite direction.
