If electric current is flow of electrons,then why current's direction is opposite to flow of electrons in a conductor?
1 Answer
The reason is historical!
Explanation:
When Benjamin Franklin first named one kind of electric charge positive and the other kind negative (although the concept of two kinds of charges, such that likes attract and opposites repel was known for a long time before him ), he had no idea that charge is conducted in metals by tiny subatomic particles (even the idea of the atom was not well established then). It's just by chance that the kind of charge that he called negative is the kind that electrons carry.
Since current has always been defined as the direction of flow of positive charge, and in most situations current is carried by electrons - that are negatively charged by this convention - the current flows in the direction opposite to the direction in which the electrons flow.
