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 meant by cut off voltage in diode?
Cutoff voltage is the point at which the battery is fully discharged. This is usually the point at which the device will shut itself off.
Why Si is used than Ge in semiconductor diode?
silicon diodes Cut in voltage is 0.7 V.but the Germanium cut in voltage is 0.3 V that's why .............
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 .
Is it possible to reduce the cut in voltage of a diode?
No,it is not possible to reduce or increase the cut in voltage of the diode after the manufacturing of the diode but we can design zener diodes of various values of cut in voltage.But it is able to do that only at the time of manufacturing
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.
Definition of cut in voltage of diode in electronics?
zener cut in voltage
What is meant by cut off voltage in diode?
Cutoff voltage is the point at which the battery is fully discharged. This is usually the point at which the device will shut itself off.

What is meant by cut in voltage?
Cut-in voltage is the value of voltage at which appreciable current begins to flow when a pn junction is forward biased.
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 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.
