## Motion of electrons is the cause of electric current.Since e flow from -ve to +ve terminal, the direction of current should be from -ve to +ve. But we take the direction of current to be from +ve to _ve.Many state the reason that "conventionally"we take the direction to be from +ve to -ve terminal.But now when it is known that elctrons move while +ve charges do not, then why does the convention remain although it is false?
