If the direction of electric current is in the direction of flow of positive charges,then why electric current is referred as scalar quantity?

Expert Answer:

A quantity which has a magnitude and direction is called a vector quantity. Current is considered to be in the direction of flow of positive charges. Current is not defined by this direction. It is conventionally fixed. Current is only specified by a number such as 5 A, 3.5 A, etc.
Hence, current is a scalar quantity and not a vector.
