The direction of electric current flow is a little difficult to understand to those who have been taught that current flows from positive to negative. There are two theories behind this phenomenon. One is the theory of conventional current and the other is the theory of actual current flow.
Also, many experiments have revealed that it is free electrons in a conductor that flows. Negatively charged electrons move from the negative terminal to the positive terminal. This is the direction of the actual current flow. In terms of circuit analysis, we normally consider the direction of electric current from positive to negative.
The movement of these charges, typically electrons in conductors, results in electric current. Electrons are negatively charged and move from the negative terminal of a battery to the positive terminal when connected in a circuit. In direct current (DC), the flow of electric charge is unidirectional, meaning the current flows in a single direction.
The net result is a massive movement of electrons from the negative terminal of the battery to the positive terminal. This is how current flows in wires and cables and most electronic components. Not all current flow is by electron movement. In some cases, the current is actually the movement of other current carriers.
In direct current (DC), the flow of electric charge is unidirectional, meaning the current flows in a single direction. Batteries and cells produce direct current. Examples of DC devices: Flashlights, mobile phones, and electric vehicles. In alternating current (AC), the flow of electric charge periodically reverses direction.
I would appreciate it very much. There is a convention for the technical direction of the current: positive current flows from the plus pole of a battery to the minus pole by convention. The microscopic details of conduction in a specific medium/conductor are a different thing. In some conductors, like metals, it is actually electrons that flow.
