How Do Current Flow In A Circuit

I will start with the direct current dc example you mention.

How do current flow in a circuit. Conventional current is the flow of a positive charge from positive to negative and is the reverse of real electron flow. The term current refers to the simple flow of electrons in a circuit or electrical system. If you have an inductance in the circuit the current will rise until the emf generated by the inductance equals the applied voltage. 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.

Ohm s law is the most important basic law of electricity. In a simple circuit current flows from the positive terminal of the battery to the negative terminal of the battery while electrons flow from the negative terminal of the battery to the positive terminal of the battery. 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. Current flow and ohm s law.

The current will then continue at a rate determined. No coils current flows according to ohm s law which is shown below. It defines the relationship between the three fundamental electrical quantities. Current flows in the opposite direction of the electron flow.

Alternating current ac and direct. Electrical current exists in two types. Electrical current is measured in amperage or amps. Current voltage and resistance when a voltage is applied to a circuit containing only resistive elements i e.
