Conventional And Electric Current

Electric current any movement of electric charge carriers such as electrons protons ions or holes.

Conventional and electric current.

The same is true for the electrical current. In the image below we can see current moving from the positive terminal of the battery through the resistance to the negative terminal of the battery. Conventional current is the flow of a positive charge from positive to negative and is the reverse of real electron flow. It is directed from the negative terminal to the positive terminal.

And we consider conventional current as the standard notation of current flow. The conventional symbol for current is i which originates from the french phrase intensité du courant current intensity. The flow of electrons from source negative terminal to positive terminal is termed as electron current. Conventional current on the other hand is the flow of positive charges and is directed from positive terminal of the battery to the negative terminal.

It states that electrons flow from positive to negative. There is often a lot of misunderstanding about conventional current flow and electron flow. Hence electric current is the flow of electrons in a circuit. The conventional current for an electron flow is positive whereas the electrical current is negative.

This illustrates conventional current flow. When so defined the current is called conventional current. Here all electrons flow from the negative terminal to the positive. These two notations are opposite to each other.

Electron current and conventional current are two types of notation we use to mention current flow in a circuit. Conventional current assumes that current flows out of the positive terminal through the circuit and into the negative terminal of the source. The i symbol was used by andré marie ampère after whom the unit of electric current is named in formulating ampère s force law 1820. The notation travelled from france to great britain where it.

Electric current in a wire where the charge carriers are electrons is a measure of the quantity of charge passing any point of the wire per unit of time. This was the convention chosen during the discovery of electricity. Conventional current flow is the one most often used. Conventional current and electron flow.

Current intensity is often referred to simply as current. Two types of current are normally employed is electric circuit one is conventional current and another one is electron current. Electric current can be either negative or positive but conventional current is always positive. For a flow of positive charges both the electric current and the conventional current are the same.
