diode is a semi conductor device and it is also unidirectional device . It will allow current to flow one side. in the process of creating diode there are different of semi conductor material are used like germanium silicon & selenium.
Some diodes are comprised of metal electrodes in a chamber evacuated or filled with a pure elemental gas at low pressure
Symbol diode
it has two terminals first one's is anode and seconds cathode.Diode consume some amount of power when they were forward bias . in the condition germanium it takes 0.3v and silicon maternal takes
0.7v. When diode is reverse bias the current will not flow.
why diode is used?
diode is mostly used in the electronic and electrical circuit there are different function of diode.Diode is used as
- rectifier
- switch
- clamper
- clipper
etc.
Advantages
- convert AC current into DC
- fast operate
- no need to warm before the operate
- low weight and small in size
- cheap in price
Disadvantages
- reverse saturation current
- noise level is high
- poor response
