Current Flow In A Circuit Direction

Then why do we have a concept of conventional current.

Current flow in a circuit direction. Hence it does not make a difference. 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. A flow of positive charges gives the same electric current and has the same effect in a circuit as an equal flow of negative charges in the opposite direction. Direction of current flow in circuit analysis.

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. In terms of circuit analysis we normally consider the direction of electric current from positive to negative. Electrical current exists in two types. Yet current is a physical quantity that can be measured and expressed numerically.

Concepts of voltage current resistance continuity and even mathematical treatments such as ohm s law chapter 2 and kirchhoff s laws chapter 6 remain just as valid with either style of notation. Technically the flow of charges be it either positive or negative is current but when we talk about circuits and electronics we tend to call it as flow of electrons which is just an oversimplification. Using the word current in this context is to simply use it to say that something is happening in the wires charge is moving. Electrical current is measured in amperage or amps.

This was the convention chosen during the discovery of electricity. Mathematically negative charge flowing in one direction is equivalent to positive charges flowing in the opposite direction. You can also liken electrical current to the quantity or volume of water flowing through a water pipe. If the two requirements of an electric circuit are met then charge will flow through the external circuit.

The term current refers to the simple flow of electrons in a circuit or electrical system. We re continuing in 7 3 on a discussion concluding capacitors we re looking at current flow in a capacitive circuit. In electronics the. Conventional current is the flow of a positive charge from positive to negative and is the reverse of real electron flow.

Even though a capacitor has an internal insulator and that s going to be right here current can flow through the external circuit as long as the capacitor is charging and discharging so as long as it s charging and discharging current can flow. This ic called as electron current. 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. Alternating current ac and direct.

By convention the flow of current is assum. The actual flow of current in a conductor is only due to electrons. Actually electrons are negatively charged hence the current due to them will be charge p.
