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 break down region of zener diode?
Zener breakdown is the phenomena wherein the Zener diode experiences reverse breakdown at a much lower voltage than a normal diode, which may breakdown in excess of 100 volts, depending on the type. This is useful because the Zener will hold the same voltage after breakdown, regardless of the input voltage, making them excellent for voltage controlled switches and references.
What is the applicatios and propertyes of diode clamping?
A: T he application are many. Basically it is used to limit and unwanted overshoot of voltage A diode will clamp the voltage or limit the voltage to .7 volts higher and no more.. It can clamp an input clamp negative or positive ringing from a collapsing coil or it can be used to clamp to a voltage.
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 input voltage at which a diode will pass current?
As close to virtually zero volts as is possible: the current will very small but there will be current. This depends on two things: the material that is used to make the diode, and whether the voltage is applied in a forward or reverse direction to the diode. A typical silicon diode will pass forward current above 0.6 V and pass no reverse current until a much higher voltage is applied (check the rated peak inverse voltage PIV)
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.

How a zener diode is used in voltage regulator under both varying input and varying load condition?
In the varying input condition, the zener diode is used in such a that any variation in the input voltage,should not in any affect the load (that is the arrangement supplies just the voltage needed by the load no matter how high or low the supply voltage might go). In the varying load condition, the zener diode is connected in such a way that any change in the load voltage should not affect the input voltage.
What is PIV in electronics?
The Peak inverse voltage (PIV) equals the peak value of the input voltage, and the diode must be capable of withstanding this amount of repetition reverse voltage. For the diode in figure, the maximum value of reverse voltage, designated as PIV, occurs at peak of each positive alternation of the input voltage when the diode is forward biased.Peak Inverse Voltage at Positive Half CycleThe Peak Inverse Voltage (PIV) occurs at the peak of each half-cycle of the input voltage when the diode is forward biased . In this circuit, the PIV occurs at the peak of each positive half cycle.
What isDifference between ordinary rectifier and precision rectifier?
A simple rectifier circuit uses a diode and there is a turn ON voltage for the diode. The input voltage has to exceed the turn ON voltage (0.6V for ordinary Si diode) before rectification is achieved. A precision rectifier is an active circuit using an opamp and a diode in the feedback loop. This overcomes the turn-on "knee" voltage. The op amp reduces the turn-on voltage of a diode in its feedback loop by a factor equal to the open-loop gain of the op amp. For practical op amp gains this reduces the forward voltage to a fraction of a mV, thus giving a "precision" or near ideal diode characteristic for the rectifier function.
What will happen when a dc source is used in front of a diode in half wave rectifier?
If the DC source biases the diode off, then the output will be zero. If it biases the diode on, then the output will be DC, with the voltage being nearly the same as the input voltage.
How do you explain the stability of output voltage in spite of input voltage changing at zener diode?
In the zener region of a diode, there is a relatively flat, low slope line for voltage as a function of current. As a result, increasing current in the zener region does not result in a significant increase in voltage - hence, voltage stability.
What is the nature of the output voltage of half wave and full wave rectifiers with that of the input voltage?
In a half wave rectifier voltage across load resistance is not consistent, because for positive pulse of input voltage diode work as a forward bias i,e half wave rectifier treat as closed circuit and for negative pulse of a input voltage diode work as a reverse bias so no current flow through circuit. therefore voltage output is not consistent. In full wave rectifier two diodes are used at the both side of secondary coil of transformer. due to that for positive pulse of input voltage one diode diode work as a forward bias another as a reverse bias. for negative pulse of a input voltage second diode work as a forward bias another as a reverse bias,so consistent voltage can be provided by full wave rectifier.the nature of output voltage of half wave rectifier and full wave rectifier is that it flows through with only one polarity either in positive or negative in the circuit.

How does clipping circuits work in lab?
A clipping circuit works by the switching action of a diode when it is used in a circuit with a source voltage that changes polarity. In the forward direction, the diode's voltage is added to any dc value that is in series with it. If the source voltage is greater than the dc value at a particular instance, the diode will limit the output to the dc value. Otherwise the output voltage will equal the input voltage.
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.
