What are the applications of photodiode?
The photodiode is widely use in day to day life means in consumer electronics and in industry. Application of photodiodes. The photodiode is used in an optical communication system. The…
Can an LED be used as a photodiode?
In most circuits, you can replace a standard silicon photodiode with an LED. Pay attention to the polarity. Also keep in mind that the LED is not as sensitive as…
How does photodiode detect light?
LEDs can also be used as photodiodes because they can emit and sense light from their junction. All PN junctions are photosensitive and can be used in a photoconductive, undistorted…
How is photodiode used to detect optical signals?
A photodiode may be used to detect optical signals as we observe the change in current with change in light intensity when a reverse bias voltage is applied. Under a reverse…
What is the difference between Photodiode and phototransistor?
One of the major differences between the photodiode and the phototransistor is that the photodiode uses a PN junction diode that converts the light energy into electrical current while the…
What is meant by avalanche photodiode?
An avalanche photodiode (APD) is a highly sensitive electronic semiconductor device that utilizes the photoelectric effect to convert light into electricity. High sensitivity and low noise, Fast reaction and Low-light…
Will the current increase in the other parallel resistors if one of the parallel resistor is removed?
Since you haven’t made any specifications, I’m getting there. Our source will provide 100v DC. The current will vary depending on the resistance. We will start with 3 resistors of…
What is Zener breakdown?
The Zener diode is a PN junction diode that was specially developed for operation in the blocking mode. In the forward bias mode, it acts as a normal diode. It has a…
Why is Darlington array not as efficient as MOSFET as a stepper motor controller?
It is due to the saturation voltage of Darlington pairs, which is normally 1 V. With a load of 1A, the device consumes 1 W. Quite a challenge for cooling…
Can waves be accelerated?
Yes, wave can accelerate . The electron matter wave in the atom is an example of a wave that keeps changing its direction. The steady state condition of quantum mechanics, however, requires that such a wave forms eigenmodes of the…
