The purpose of a diode is to direct the flow of current in a circuit. Diodes function by allowing current flow in only one direction (acting as a short when current is applied at one end) and resisting current flow from the opposite direction (acting as an open circuit). Electronic devices such as full wave rectifiers use a series of diodes to convert AC to DC current.
It's a high voltage diode, typically used in microwave ovens.
zener diode is a revers bias diode which used for voltage regulation.
Very often in translations from German to English the term 'free wheeling diode' for 'Freilauf-Diode' is used. Generally the correct translation for this term would be 'recovery diode'. The usage of the term 'free wheeling' only will be correct in mechanical aspects, e.g. the rear wheel of a bicycle or the clutch of the transmission line of a car.
A diode is a one-way gate for electrical current to flow through. You must have the right size diode for the amount of current that will be used in your circuit. The stripe on the diode is your output end. That is, the current must enter your diode at the non-stripe end and leave at the end with the stripe. This coincides with the diode symbol used on your schematic. If your diode is in backwards, the circuit will not work as the gate in the diode will block the current just the way it should.
to limit the voltage or regulate the same.
yes, diode can be used as rectifier diode to convert ac to dc
A diode is used primarily as a Rectifier
yes ofcourse diode can be used as rectifier but it's an uncontrolled rectification.
varactor diode is a correct answer
zener diode
It's a high voltage diode, typically used in microwave ovens.
The difference between the pn-junction diode and the zener diode is that the pn-junction diode is used for rectification while the zener diode is used for rectification and stabilization. Also, the zener diode can function in the breakdown region while the pn-juntion diode can not function in that regime.
A zener diode cannot be used as switch.
The use of the pn diode is for rectification. It can also be used as a switch.
A Photo-diode is used to receive light. whereas the L.E.D. is a Light Emitting Diode.
zener diode is a revers bias diode which used for voltage regulation.
