Electric A Current

The electrical current is measured in ampere amp unit.

Electric a current.

An electric current is the rate of flow of electric charge past a point or region. In alternating current the motion of the electric charges is periodically reversed. The international system of units defines the ampere in terms of. The charge can be negatively charged electrons or positive charge carriers including protons positive ions or holes.

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. More specifically the electric current is the rate of charge flow past a given point in an electric circuit. When two point of different electric potential are connected by a conductor charge flows so long as a potential difference exists. It is named after andré marie ampère 1775 1836 french mathematician and physicist considered the father of electrodynamics.

Electric current is defined as the rate at which charge flows through a surface the cross section of a wire for example. The difference in electrical potential between two points measured in volts. Electric charge is carried by charged particles so an electric current is a flow of charged particles. An electric current is said to exist when there is a net flow of electric charge through a region.

A often shortened to amp is the base unit of electric current in the international system of units si. Despite referring to many different things the word current is often used by itself instead of the longer more formal electric current. 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. Electric current is electric charge in motion.

An electric current is a flow of electric charge in a circuit. The ampere ˈ æ m p ɪər æ m ˈ p ɪər or ˈ æ m p ɛər uk symbol. It is said that there is a current a flow of charge. In direct current it is not.
