What is the function of photodiode?
the function of a photodiode is produce some reverse current in the external resistor of circuit.
Which of the following statements is (are) true about reverse bias breakdown due to impact ionization and Zener tunneling?
Reverse bias breakdown due to impact ionization is when electrons are accelerated by the electric field to such high speeds that they knock other electrons out of the atoms they collide with. This process releases a large amount of energy, which can cause the breakdown of the material. Zener tunneling is when the electric field is strong enough to cause the electrons to tunnel through the potential barrier. This process can also cause the breakdown of the material.
Why emitter bias circuit is called self bias?
emitter bias provides a feedback to the circuit so that circuit remains in linear regionn
What difference between photocell and solar cell?
A photocell is operated under an external bias which is reverse bias. A solar cell works on the same principle of photo voltaic effect as the photo cell except that no external bias is applied and the junction area is kept much larger for solar radiation to be incident. a solar cell does not draw current but supplies the same to the load
What is an effect of bias?
It makes an experiment less objective.
What are the different types of biasing?
Fixed Bias,Self Bias, Forward Bias, Reverse Bias
Characteristics of curve of an ideal diode with diagram?
0V forward bias knee voltage0 ohm forward bias resistance0A reverse bias currentinfinite ohm reverse bias resistanceno parasitic capacitance or inductance
What is the reverse bias diode?

What are the bias conditions base collector junctions for a transistor to operate as a switch?
Reverse bias
What are the two bias conditions for a diode?
The two bias conditions for a diode are forward and reverse
Does diode flow current in reverse bias?
Diodes will have a small leakage current in reverse bias. In most cases, this current can be considered insignificant and ignored.
What will happen if no applied bias In forward bias and reverse bias?
If no forward or reverse bias is applied from outside then the diode or transistor(I'm not sure for which did you ask) is in internal equilibrium. thus there's a field created in each junction which prevents the flow of charges across it..
Reverse saturation current of Ge diode?
Reverse saturation current of germanium diodeThe current that exists under reverse bias conditions is called the reverse saturation current. Reverse saturation current of the germanium diode is typically 1 micro ampere or 10-6 a.At a fixed temperature, the reverse saturation current of a diode increases with increase in applied reverse bias. In reverse bias region the reverse saturation current also varies with the temperature.
A zener diode is invariably used with?
Reverse bias
What is the voltage drop of an ideal diode?
forward bias 0 volts, reverse bias infinity volts.
Forward bias and reverse bias?
forward bias is in the direction a junction or vacuum tube wants to conduct currentreverse bias is in the direction a junction or vacuum tube opposes conducting current
Why ammeter is connected in different way in forward and reverse bias zenner diode?
The ammeter is connected in different way in forward and reverse bias zenner diode. So that all of the board will work right going forward and reverse.
