Functions of Rectifier Diodes

Download "Chapter II : Diodes" (PDF:895KB) 

A characteristic of diodes is that current flows (forward direction) or current does not flow (reverse direction) depending on the direction of applied voltage. This works to convert alternating current (AC) voltage to direct current (DC). The electrode terminals are called the anode (A) and the cathode (K), and current flows when the anode electrode is at positive potential.
