Is it the value of input voltage equal the value of output voltage?
No. There are several factors that may affect the output voltage. For instance: Resistors, Transformer, Voltage regulators and others that can control the output voltage to a certain level.
A typical value of reverse breakdown voltage in a diode is?
50V or larger
What is zener dioide?
Zener diode can be defined as diode which allows current to flow in the forward direction in the same method as an ideal diode, but will also allow it to flow in reverse direction when the voltage is above definite value known as the breakdown voltage
What is the maximum DC voltage you could expect to obtain from a transformer with an 18V rms secondary using a bridge rectifier circuit with a filter capacitor?
The maximum DC voltage you could expect to obtain from a transformer with an 18V rms secondary using a bridge rectifier circuit with a filter capacitor is about 24V.This assumes a truly sinusoidal AC waveform, and a forward conductioin voltage of 0.7 volts across each diode.Multiply 18 by the square root of two, and subtract two times the diode voltage.The maximum is the peak value. If there is any load on the output, there will be some ripple, but the peak value will still be around 24V.To calculate the output voltage of single phase diode bridge it is reasonable to assume a filter capacitor exists across the output and realize that it will be charged to the maximum voltage available to it.
At what value reverse breakdown voltage should ouccer of normal diode?
its about 1000 v
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.

You want to know about the voltage selector circuit using transformer?
the voltage selector circuit is used for converting input electrical energy through the voltage selection circuit,which is arranged within the transformer body with its two ends electric allay connected to an input port and an output voltage connection device must be plugged in a socket portion on the transformer body to initalize a micro control unit through feedback to change a volatage value sent to a voltage transformer unit and in turn change the voltage of output electrical energy until a display device displays an ideal output voltage value. Then, the user removes the connection device, and the voltage value of the input electrical energy is converted into corresponding to the selected
What is the value of the breakdown voltage for zener diode?
It depends on the particular diode. They come in all different values.
Why rectified output is more than ac input voltage?
It is not. It is just a matter of interpretation. When you measure an AC voltage, you normally measure its average, or RMS, value. In a typical 117 VAC system, for instance, the voltage is alternating between +165 V and -165 V in a sinusoidal form. If you rectify that with a diode, and then filter it with a capacitor, the voltage will be 165 VDC. (Less, of course, by the forward bias drop of the diode.) That is simply the peak value of the original voltage.
A typical value of reverse breakdown voltage in a diode is?
50V or larger
What value resistor and diode would you need to drop voltage from 12 volts ac to 1.2 volts dc?
I'm not sure you understand what you're asking. A diode will have a voltage drop of ~.5-.7 volts. If you put a diode and resistor in series, the voltage across the diode will be .5 - .7 volts, and the voltage drop across the resistor will be (supply voltage - diode voltage drop). If you are trying to rectify to DC, you need at the least a half wave rectifier (two diodes), and some system to remove the ripple. The rectifier simply chops the AC waveform, so for the part of the supply sine wave that is ~.5 or less, the output of the rectifier will be zero. The top part of the sign wave will show up on the output of the rectifier, but will be slightly smaller (due to the voltage drop across the diode). You'll need to get ride of this rippling for true DC. One fairly easy way to do this is to use a zener diode. It will attempt to keep the voltage drop across it the same, so purchase a 1.2 volt zener diode. The problem with this is the zener diode will saturate if you have too heavy a load. What I've done on simple projects is to use a zener diode to bias the base to collector voltage of a transistor, with the emitter acting as the output (an NPN BJT usually). I also used a fairly large capacitor to help minimize the ripple as well, although this may not be necessary for you.
What are some applications of Zener diode?
A zener diode is like a regular diode when connected in forward bias which means it will control the flow of the electricity throughout the circuit. Usually you'd find a zener diode in a reverse bias mode because of its purpose which is it has a breakdown voltage value of 5.6v; this shows that the circuit output voltage will be regulated at the same value of 5.6v. It also has the ability to change its own internal resistance based current flow passing through it helping sustain a fixed voltage of 5.6v. The benefits of a zener diode are that it is a less cost effective voltage regulator, its simplicity is based on the fact it's a diode with two overall purposes. The main purpose of a zener diode is to maintain a fixed voltage; in order for this to happen it must lower or raise its resistance depending on the actual current flowing throughout the circuit. If the current increases the zener diode will raise the resistance in order to maintain the fixed voltage. If the resistance lowers the diode will raise it because the fixed voltage should be at 5.6v, and works in reversed biased.

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.
