What is dropper diode voltage regulator?
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.
What is the effect of diode voltage drop as the output voltage?
The effect of diode voltage drop as the output voltage is that the input voltage will not be totally transferred to the output because power loss in the diode . The output voltage will then be given by: vout=(vin)-(the diode voltage drop).
What is the cutting voltage of a silicon diode?
It is not 'Cutting voltage' but it is Cut-in voltage'. It is the voltage at which the diode turns ON. For silicon it is 0.7v. After reaching 0.7V diode current starts increasing rapidly for little increase in voltage.
How is the zener diode connected to protect the load?
A: A zener is a diode that if reversed voltage is applied will conduct at a certain voltage. This diode zener therefore will conduct at a preset voltage limiting the over voltage to the diode conducting voltage and no more so the load can see the voltage up to the zener voltage and no more because the zener will sink the extra current from over voltage situation.
What is the purpose of the zener diode in a power supply?
to limit the voltage or regulate the same.
Break down voltage?
The breakdown voltage of an insulator is the minimum voltage that makes it partially conductive electrically. On the other hand, the breakdown voltage in a diode refers to the minimum reverse voltage to cause it to conduct in reverse.
Why the knee voltage for germanium is 0.2v?
The knee voltage for germanium is around 0.2V because this is the point at which the diode starts conducting current in a forward bias condition. Below this voltage, the diode remains non-conductive. This specific value is determined by the band gap energy of germanium.

How does the cut in voltage effects the output of a diode clipper?
For answering this question we have to consider the constant voltage drop model of the diode which says that if voltage across diode is less then its cut in voltage than assume diode to be open circuit and if it is greater then assume diode to be short circuit.Till the input voltage is less than the cut in voltage, diode is open circuit(thus no current through the circuit). Thus entire input voltage appears across the diode as output.When input voltage is greater than or equal to cut in voltage, then short circuit the diode. Thus, there will be no voltage drop across the diode as output.Thus cut in voltage decides when to consider the diode open circuit and when short circuit. It decides when the diode will have output when it will not.

What is the forward breakdown voltage for in4007 diode?
there is no forward breakdown voltage for any diode
What do you mean by peak reverse voltage of semiconductor diode?
Peak reverse voltage of a diode is the maximum reverse bias voltage can be applied to diode which does not cause break down.
What is the condition that prevent the current to pass across diode?
if the voltage across the diode is less than the cut-in voltage of that particular diode .
Does the material of the diode depends on break down voltage?
A Germanium diode has a much lower breakdown voltage than a silicone diode.
What is the difference between a 1N4007 diode and a 1N4007S diode what does the s do?
The difference in the 1N4007 diode and the 1N4007S diode is the voltage. The 1N4007S has a higher voltage but the meaning of the S is not listed.
What is the significance of piv of diode?
The PIV (Peak Inverse Voltage) rating of a diode is the maximum voltage that you should apply to it in the reverse biased condition. Exceeding this voltage can destroy the diode.
