Which is N in Diode?
N in diode is an abbreviation for the word “nondirectional” which refers to a type of electrical current flow. This type of electrical current can move both ways, meaning that it can travel in either direction through a circuit. Diodes are semiconductor devices that allow electricity to flow in one direction only and so they are used to control the direction of current.
The letter N often appears before the numbers that appear after the diode’s name, such as 1N4004 or 1N4007. This indicates that the diode is non-directional in nature and will not restrict current flow in either direction.
