Electric A Current

An electric current is the rate of flow of electric charge past a point or region.

Electric a current.

An electric current is a flow of electric charge in a circuit. If the two requirements of an electric circuit are met then charge will flow through the external circuit. The charge can be negatively charged electrons or positive charge carriers including protons positive ions or holes. The international system of units defines the ampere in terms of.

More specifically the electric current is the rate of charge flow past a given point in an electric circuit. It is said that there is a current a flow of charge. Using water pipe analogy we can visualize the electrical current as water current that flows in a pipe. Electric charge is carried by charged particles so an electric current is a flow of charged particles.

Despite referring to many different things the word current is often used by itself instead of the longer more formal electric current. The difference in electrical potential between two points measured in volts. 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. The electrical current is measured in ampere amp unit.

Electrical current is the flow rate of electric charge in electric field usually in electrical circuit. In alternating current the motion of the electric charges is periodically reversed. The adjective electric is implied by the context of the situation being described. When two point of different electric potential are connected by a conductor charge flows so long as a potential difference exists.

An electric current is said to exist when there is a net flow of electric charge through a region. Using the word current in this context is to simply use it to say that something is happening in the wires charge is moving. Electric current is electric charge in motion.

It is named after andré marie ampère 1775 1836 french mathematician and physicist considered the father of electrodynamics. It can take the form of a sudden discharge of static electricity such as a lightning bolt or a spark between your finger and a ground light switch.
