Expert Answer
The concept of electricity was established before the discovery of electrons. So, it was believed that the passage of current is due to the flow of positive charges. This is what we call the conventional flow of current, i.e. in the direction of flow of positive charges. After the discovery of electrons, it was observed that the electron are the particles that flow in a conductor. Electrons being negatively charged flow from the negative terminal to the positive terminal of the voltage source. So, the actual direction of current should be from negative to positive terminal. However, the conventional direction had already been established firmly in scientific fraternity. So, the current flow is considered in the direction opposite to the direction of flow of electrons.
