What is current and its types
Current
Current is the flow of electrical charge carriers, and usually current is the flow of electrons. Current flows from positive to negative. Current is measured by the number of electrons passing through the cross-section of a conductor in one second, and the common symbol for current is I. Also the standard unit is the ampere, symbolized by A. An electric current always creates a magnetic field and the stronger the current, the stronger the magnetic field.
And there are two types of current namely AC current and DC current.
1. AC Current
AC current is also called alternating current, this current flows first in one direction and then in the other direction and this stream flows frequently.
2. DC Current
DC current is also called direct current, this current always flows in the same direction.
Current Density
Current density per unit cross-sectional area is known and is expressed in amperes per square meter, amperes per square centimeter or per square millimeter. Also current density can also be expressed in amperes per circular mil.
What do you mean by current?
Current is the flow of electrical charge carriers, usually electrons. Basically the flow of current is from positive current to negative current
What are the two types of flow?
Direct Current (DC) and Alternating Current (AC).
