How does conventional current flow

In general, high school Physics and two year technician programs use Electron Flow. But three year technologist and university engineering programs use Conventional Current. Certain symbols ex. Right-hand rules were created using Conventional Current. Changing from Conventional Current to Electron Flow would cause a degree of confusion for old and new students and errors would occur, so Conventional Current was kept to ensure there was no confusion with those already trained with Conventional Current.

Two systems may seem confusing, but as long as usage is consistent, it really is not! You must realize what convention is being used because the rules change. Throughout this course, Conventional Current is used. Therefore always assume current flows out of the positive terminal of the source. Using the right hand rule for the conventional current in the wire, the right thumb is pointed along the wire pointing to the left at the top of the circuit.

This is conventional current. The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery.

Electrons would actually move through the wires in the opposite direction. Electrons being negatively charged flow from the negative terminal to the positive terminal of the voltage source.

So, the actual direction of current should be from negative to positive terminal. So, the current flow is considered in the direction opposite to the direction of flow of electrons. Conventional current or simply current, behaves as if positive charge carriers cause current flow. Conventional current flows from the positive terminal to the negative. In general, analyzing an electrical circuit yields results that are independent of the assumed direction of current flow.

Georg Ohm, in full Georg Simon Ohm, born March 16, , Erlangen, Bavaria [Germany]—died July 6, , Munich , German physicist who discovered the law, named after him, which states that the current flow through a conductor is directly proportional to the potential difference voltage and inversely proportional to ….

Current direction In a direct current DC circuit, current flows in one direction only, and one pole is always negative and the other pole is always positive. When the capacitor is connected to the DC voltage source, initially the positive terminal of the DC supply pulls the electrons from one terminal and pushes the electrons to the second terminal.

Later when the direction of the AC supply changes the capacitor will discharge. Direct current DC is an electric current that is uni-directional, so the flow of charge is always in the same direction. As opposed to alternating current, the direction and amperage of direct currents do not change.

It is used in many household electronics and in all devices that use batteries. Begin typing your search term above and press enter to search. Press ESC to cancel. Skip to content Home Helpful tips How does the conventional current flow in a circuit?
