From now on this is what we mean by current. Understand the difference between electron flow and conventional current flow.
Electron Flow is what actually happens.
What is the conventional direction of flow of current. A SIMPLE explanation of the direction of conventional current flow. Hence it does not make a difference. If the current is measured for a flow of positive charges the conventional current is in the same direction as the charge flow.
This convention was established when electricity was first discovered but its incorrect. Mathematically negative charge flowing in one direction is equivalent to positive charges flowing in the opposite direction. This convention of flow of current is so firmly established that it is still in useThus the conventional direction of flow of current is from the positive terminal of the cell to the negative terminal of the cell through the external circuit.
The electrons flow out of the negative side of the battery through the circuit and. The magnitude of the flow of current at any section of the conductor is the rate of flow of electrons ie charge flowing per second. Electrons would actually move through the wires in the opposite direction.
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. This was the convention chosen during the discovery of electricity. Negatively charged carriers such as the electrons the charge carriers in metal wires and many other electronic circuit components therefore flow in the opposite direction of conventional current flow.
Conventional Current assumes that current flows out of the positive terminal through the circuit and into the negative terminal of the source. It states that electrons flow from positive to negative. And the current direction here the conventional current direction or just plain current direction is in that direction.
In general current means conventional current it is measured by Ampere. Conventional current flows from the positive terminal to the negative. Conventional current flow from positive direction to negative direction where as electric current flow from negative to positive.
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. The direction of conventional current is arbitrarily defined as the direction in which positive charges flow. The direction of an electric current is by convention the direction in which a positive charge would move.
The electric current flow starts from the negative terminal to the positive terminal of a battery as the electron will flow from the positive terminal to the negative terminal. Conventional Current Conventional current or in other words the standard current is measured in the opposite direction of the flow of the negative charges ie. Conventional current is the flow of a positive charge from positive to negative and is the reverse of real electron flow.
Conventional current flow is the one most often used. Conventional current ﬂows from the positive terminal to the negative. Here the current flow due to positive charges.
However because we tend to associate the word positive with surplus and negative with deficiency the standard label for electron charge does seem backward. In conventional current the flow of electron is assumed as flow of proton in opposite direction. Conventional Current Electron Flow Electric current is the flow of electrons from the negative terminal to the positive terminal of a cell.
In an electric circuit when the electric charge is flowing in one direction the current will flow in the opposite direction. Thus the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. In terms of circuit analysis we normally consider the direction of electric current from positive to negative.
Out of the positive and back into the negative. Thus the standard direction of flow of current is from the positive terminal of the cell to the negative terminal of the cell through the external circuit. All descriptions of electronic circuits use conventional current so if you see an arrow depicting current flow in a circuit diagram you know it is showing the direction of conventional current flow.
Conventional current is nothing but a flow of positive charge carriers causes current to flow. Because of this many engineers decided to retain the old concept of electricity with positive referring to a surplus of charge and label charge flow current accordingly. This illustrates conventional current flow.
Mathematically it is represented by. This is because electrons are negatively charged and want to move away from the negative terminal and head towards the positive terminal. Current Flow Conventional Current assumes that current flows out of the positive side of the battery through the circuit and back to the negative side of the battery.
Conventionalcurrentor simply current behaves as if positive charge carriers cause current ﬂow.
