Electric Current Current is the flow of charged particles through a conducting medium, such as a metal wire. In other words, electric current is a measure of the amount of electrical charge transferred per unit time across any cross-section. If dq be the charge flowing through a given cross-section in time dt, then electric current āIā through the same cross-section The S.I. Unit of electric current is ampere having symbol A. The electric current through any cross-section is 1 ampere if 1 coulomb charge flows across it in 1 second. Thus, ampere= coulomb per second A = Cs -1 The direction of electric current is taken as the direction of flow of positive charge.

It means the direction of electric current is opposite to the direction of electrons. On the basis of variation of its direction, the two main types of current are: Direct Current in which the flow electric current is only in one direction and Alternating current whose magnitude changes with time and reverses its direction periodically. Electric current is a scalar quantity. Although electric current possesses both magnitude and direction, yet it is not a vector quantity because it does not obey the rules of vector addition. Thus, the arrow heads used to indicate the direction of current in electric circuit is simply indicate the direction of flow of positive charge. Electric currents add and multiply like scalar quantity. Current Density Current density as word itself suggests is the density of current.
It is an another way to describe the flow of charge. Idhu Kathirvelan Kadhal Tamil Movie Mp3 Songs Free Download Starmusiq. The electric current density at a point in the conductor is defined as the electric current per unit area around the given point and in a direction perpendicular to the area.
