Diodes have several applications such as voltage rectification and have anode and cathode polarization. A diode bridge is actually a voltage rectifier and this is one of the most common functions of a diode, the diode theory shows that the diode conducts electric current in only one direction which makes it possible to bar a half-cycle of a voltage sine wave. Every diode presents a voltage drop, in general-purpose diodes this drop is approximately 0.7V. Some diodes can conduct only when they receive light and others, on the contrary, emit light when they conduct electric current, these called LEDs are the best known diodes.

Presenting the symbology and how to interpret this symbol. We cover the following items throughout this video: Definition of a diode, the LED diode being the best known. Analogy of a resistor with a one-way water valve Symbology of a diode and its polarity, explanation of what anode and cathode are. Main uses of diodes. Voltage drop across the diode and reverse bias. Power and switching speed of a diode. Types of diodes: General use. Zenner LED Signal diode Photo diode Varicap diode Rectifier diode. Use of diodes in a rectifier bridge. How to test diodes. Parts highlighted in this video (edit annotations): 00:18 - A very common use of a diode is the use of an LED diode to function as a flashlight. 01:15 - A power supply that uses rectification can have several internal diodes, the main ones connected to each other to form a rectifier bridge. 02:34 - Just like resistors, diodes undergo the Joule effect when a current flows through them. 04:49 - When studying diodes and the forms of rectification, it is important to understand what voltage and direct and alternating current are.
