Electric current is the flow of electrons. So, it should flow from the negative to the positive terminal. But my teachers say that the conventional direction of the current flow is high (positive terminal) to low (negative terminal) potential. Which statement is true? If both are true, then why? And please explain to me the difference between Direct and Alternating current. Please help, my exams are coming.
