Electrons do not flow, but they might be though of as 'flowing' as they transfer charges between them. The reason that electron flow is the opposite direction from current is that historical theories of electrical flow (current) treated it as a movement of positive charges rather than negative charges.There is no actual difference that could be discerned, except that we now know that negative charges (electrons) constitute the basis of most common electricity.
when a negative and a positive charges attract. or when there is a closed circuit.
Negative side
Electrons are negatively charged particles. The reason the negative side of your D battery is negative is because that's where the free electrons are. The positive terminal is starved or has a deficit of electrons. The negatively charged electrons naturally want to fill the 'holes', in atoms lacking an electron on the positive side. Thus electron flow is from negative to positive. Conventional current flow assumes that current flows out of the positive terminal, through the circuit and into the negative terminal of the source. This was the convention chosen during the discovery of electricity. They were wrong!
Electron flow is from negative to positive. Conventional current flow is from positive to negative.
The continuous flow of positive charges is called current
Charges always flow from positive to negative.
A continuous flow of negative charges is called an electric current.
The continuous flow of positive charges is called current
Conventional current flow is the flow of positive charges, or the equivalent flow of positive charges. That is, if what flows is really negative charges (for example, an electron), which flow in one direction, the "conventional current" flows in the opposite direction.
Electrons are a negative charge. Using conventional notation current flows from positive to negative poles of a battery, for example. In electron flow convention the electrons flow from negative to positive.
Electrons are a negative charge. Using conventional notation current flows from positive to negative poles of a battery, for example. In electron flow convention the electrons flow from negative to positive.
That means that you consider the flow of a POSITIVE charge. If negative charges happen to flow in one direction (as is often the case), you consider the equivalent flow of positive charges in the opposite direction.
Current means flow. Electric current means flow of electric charges Now there are two kind of charges. They are positive and negative But current is defined as the flow of positive charges But in metallic wires there is no chance for positive charges to flow through. Only loosely bound electrons with negative charge are capable of flowing. So current is case of metallic wire is due to electrons. So we have to assign as "conventional current". Conventional current is always opposite to the flow of electron flow Now from a battery current (conventional) flows right from positive polarity to the negative polarity. But within batter is has to flow right from negative to positive so as to complete the circuit of flow.
Because in an unbalanced system, the positive end a positive charge, and the negaticve end has a negative charge. Though current (which is reletive to the "positiveness" of an area) flows from positive to negative, electrons flow from negative to positive.
Conventional current flow refers to a flow of positive charges. It is a kind of ficticious current. If - as is often the case - the real current is an electron flow (negative charges), then the conventional flow is a current in the opposite direction as the electron movements, since this would have the same effect (for example on the magnetic field, or on conservation of charge).
Old (very old) tradition, when electricity was assumed to flow from positive to negative. (They hadn't figured out electrons yet.)
