zener diode
It's a high voltage diode, typically used in microwave ovens.
diode is made by joining a P and N type semiconductor materials
It is considered a diode, a Light Emitting Diode (LED).
The dropper diode voltage regulator is a type of voltage regulator. It is comprised of a single diode that serves as the voltage regulating device.
The read type diode are called impatt diode
You need to apply an external voltage across the diode. The negative terminal must be connected to the N type material.
zener diode
A diode modulator is a type of AM modulator constructed using diodes. One type of diode modulator is the ring modulator shown in the image.
An ordinary diode, no. It has nowhere to get energy from.But a solar cell is a type of diode that converts light to electricity. So it is a diode that can power a circuit. So yes, there is one type of diode that can power a circuit.
varactor diode is a correct answer
It's a high voltage diode, typically used in microwave ovens.
A photo diode
A diode has a n type and a p type materials that's why it's called a pn-junction device
infrared diode
diode is made by joining a P and N type semiconductor materials
It is considered a diode, a Light Emitting Diode (LED).
