What is a diode

This video tutorial explains the function and application of diodes in electronic circuits. It covers the basic structure of diodes, including anodes and cathodes, and their role in allowing current to flow in one direction. The video uses a water analogy to illustrate diode functionality and discusses the difference between electron flow and conventional current flow. It also explains how diode orientation affects circuit behavior, introducing concepts like forward and reverse bias. Additionally, the video explores the use of diodes for circuit protection and converting AC to DC, detailing the rectification process and how capacitors can smooth the output.

Describe how diodes can convert alternating current (AC) to direct current (DC).
