Electric Current Vs Conventional Current

The flow of positive charges or proton is called conventional current.

Electric current vs conventional current.

In general analyzing an electrical circuit yields results that are independent of the assumed direction of current flow. It has opposite direction of electric field. Current flows from the negative side of the battery through the resistance to the positive side rather than vice versa. This was the convention chosen during the discovery of electricity.

Conventional current assumes that current flows out of the positive terminal through the circuit and into the negative terminal of the source. It is important to realize that the difference between conventional current flow and electron flow in no way effects any real world behavior or computational results. We need a notation to do some calculations like in kirchhoff s law. It has same direction of electric field.

These two notations are opposite to each other. The conventional current for an electron flow is positive whereas the electrical current is negative. For a flow of positive charges both the electric current and the conventional current are the same. Electric current can be either negative or positive but conventional current is always positive.

Proton moves from positive to negative. Electron flow is simply the opposite of conventional current flow. Electron flow is what actually happens and electrons flow out of the negative terminal through the circuit and into the positive terminal of the source. And we consider conventional current as the standard notation of current flow.

So if the arrow from the picture above were at the bottom of the circuit diagram this would illustrate electron flow. Current most important term in electricity if you wanna know about electricity you need to understand current in this video i explained you a little term of.
