we know that,after the discovery of electrons, we got to know that
electrons are the particles that flow in a conductor electrons
being the negatively charged particles flow from the negative
terminal to the positive terminal and for current now, electric or
conventional current is the rate of flow of charge so, the
direction of the current should be same as the direction of the
charge, i e positive charge(conventionally), so the direction is
opposite to the flow of the negative charge(flow of electrons)
hence, the direction of the flow of electrons is opposite to the
direction of electric(or conventional) current
