Ans. CONVENTIONAL CURRENT
The current flowing from positive to negative terminal of a battery due to the flow of positive charges is called conventional current.
In a metallic conductor, current is always due to the flow of free electrons. But we suppose that same amount of positive charge also flows in the opposite direction. As electric current is measured by the effect which it produces, therefore, we can say that a current produced due to the flow of negative charges is equivalent to the flow of an equal amount of positive charge. This equivalent flow of positive charges is known as "conventional current". Thus, we assume that electric current is always due to the flow of positive charge.
