A LED is a p-n junction diode that is capable of emitting light. An LED operates just like a regular p-n junction diode. Diodes must be forward biased for current conduction.What differentiates an LED from a regular diode is the semiconductor material used to form the p-n junction - regular diodes a

First let me start by defining what an LED light bulb is.  The LED light bulb is actually a cluster of individual units.  These clusters produce light, different combinations gives us different colors.  This lighting falls in a category call SSL (Solid State Lighting).  Simply pu

Testing diodes is different from testing a resistor because you need a skill to do it. If you do not know or wrongly test a diode you will be unable to repair the equipment. A bad diode you think it is good. This will definitely waste your precious time.A rectifier diode can fail in one of the four

You might have heard of diode laser hair removal. This article explains what is diode laser hair removal, the good and the bad things about it.What Actually Is This Diode Thing?The diode laser is an extremely proficient machine made up of tiny diodes or semiconductors. They are assembled together to

Many technicians are confused on how to really read a zener diode code. There are many types of code number indicated on it's body. The look and shape of a zener diode sometimescan be mistaken to be a normal signal diode. To differentiate it, is by looking at the codenumber on it's body- whether it
