A PN junction is the boundary between p-type and n-type semiconductors, crucial for the operation of diodes, transistors, and other semiconductor devices. It allows current to pass in one direction while blocking it in the opposite direction, functioning as a rectifier and enabling the control of electronic signals.

The concept of 'current direction' refers to the orientation or path along which an electric current flows within a circuit or conductor. Understanding current direction is essential for analyzing and designing electrical systems, as it affects the behavior of circuit components and the overall functionality of the system.
