Detailed explanation-1: -Electric current is due to the continous flow of electrons in an electric circuit. The conventional direction of current is taken from the positive terminal to the negative terminal of the cell. The flow of electrons is from the negative terminal to the positive terminal of the cell.
Detailed explanation-2: -By convention, we define positive direction of current to be in the direction a positive charge would move. Electrons (with their negative charge) move in the opposite direction of the positive current arrow.
Detailed explanation-3: -The reason why current flows opposite to that of electrons is due to history. The electrons were discovered much later electric currents were discovered. So, it was thought that it the movement of positive charges which causes currents. So, the direction was defined from the positive terminal to the negative terminal.
