Independent of the type of charge metal carriers have, a conventional current is defined as electron flow in the same direction as positive charges.
Why does current flow in the opposite direction to electron flow? This statement is technically false – current is the rate of flow of charge. Hi, why the electric current flows in opposite direction of electrons? If current is just the movement of charged particles, why do the all have to move in the same direction?
For example, if you reverse-bias a diode (connect the positive terminal to the n-type side and the negative terminal to the p-type side), the positive "holes" are attracted to the negative terminal and the electrons are attracted to the positive terminal. If you believe that all currents are electron-flows, then you might become confused.
A flow of positive charges gives the same electric current, and has the same effect in a circuit, as an equal flow of negative charges in the opposite direction. The direction of conventional current is always given by the direction in which positive charge moves. Since current can be the flow of either positive or negative charges, or both, a convention is needed for the direction of current that is independent of the type of charge carriers . electrons) in the opposite direction. In fact, often you will hear people state that current is the flow of electrons. This can be achieved either by moving positive charges in this direction, or by moving negative charges (ie. So if you have metals in which the charge of the carrier is negative, the electrons will be traveling in the opposite direction as the current. ? Question: Why do current flows in the opposite direction of electrons movement? Its said that electrons flow in the direction opposite to the flow of current;then why does electron never get vanished when we switch on a fan and current flows from switch board to fan?
In fact, electric current is not a flow of electrons.
