What is the peak value of the input to a half wave rectifier if the half wave rectifier is 10V?
In this case, the peak voltage, which is half the peak to peak voltage, is 100 volts. Additionally, the half-wave rectifier will only provide an output for half the input cycle. In the case of a full wave rectifier, the RMS output voltage would be about 0.707 times the value of the peak voltage (100 volts), which would be about 70.7 volts. But with the output operating only half the time (because of the half wave rectification), the average output voltage will be half the 70.7 volts, or about 35.35 volts RMS.
What is need of voltage follower circuit?
It's a buffer circuit - it provides a high impedance input, and low impedance output with ~ unity gain. If you have a circuit that cannot drive much power, you can use a voltage follower to help. Also, if the input or output of a circuit needs to stay a specific value, such as with filters, you can easily control this due to the isolation the voltage follower provides.
Why you use auto transformer in a substation?
An autotransformer is different from a "normal" transformer in that it uses the same winding for both input and output, with a tap somewhere along the winding for an additional connection for the input or output (whichever is the smaller value).When an autotransformer is configured to output a lower voltage than the input, the input AC line is connected to the ends of the winding and the output line is connected between one end of the winding and the tap at some midpoint that is proportional to the difference between the input voltage and the desired output voltage. The input voltage induces a magnetic field in the core, and the magnetic field then induces a voltage between the tap and the common end of the transformer. To use an autotransformer to output a higher voltage than the input, the input is connected between the tap and the common end, and the output is connected between both ends.Autotransformers are most often used as variable transformers with a sliding tap that runs along the outside of the winding which is wound around a toroidal core. Moving this tap changes the output voltage of the transformer. A major disadvantage of the autotransformer is that it doesn't completely isolate the output side from the input side, and dangerous voltages and currents can appear on the output side, especially DC voltages and currents which can travel through the coil unimpeded.
How do you test a stick welder transformer?
This could be dangerous if you aren't very careful. Take the transformer out of the welding machine. Put it on a wooden bench. Apply 12 volts to the input side with a car battery. Measure the input volts with a volt meter and write down the value. Then use your volt meter to measure the output voltage. If you have no output voltage then your transformer is obviously blown. You should read an output voltage that is higher than the input voltage based on the number of winding in the coil and/or the manufacturers specifications. According to Faraday's law the only output voltage you will read is at the exact time power is applied to or taken away from the input when using dc power. Otherwise you will have to apply ac power which is much more powerful ( and more dangerous ) than the 12v dc. Your volt meter may not be designed to read high enough voltage for the output you would see with 110 v ac.
What is the purpose of a resistor applied to the base of a transistor?
Any system you design will have an input and an output. The output will connect to the input of another system which will load it, so when you are designing any system you have to consider how loading it will effect the circuit performance.
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.
What is the tripler's output voltage if the input to this voltage tripler is a sine voltage and it has an rms value of 14 V?

Why common emitter configuration is mostly used for transistor as switch?
because in ce configuration value of input voltage requried to make the transistor on is very less value of the output voltage or output current
Can a digital circuit produce the same output voltage for different input voltage values explain?
No, value of output voltage depends upon the value of input voltage and digital can not produce the same output voltage for different input values. For example, suppose in a digital circuit two switches are connected. A closed switch is represented by 1 and an open one by 0. If there are two switches and we say that they are in state 1, then it would mean that both of them are closed. In this circuit after connection with the battery some current would pass so we call this current as output.Depending upon the states of the switches, the current either would pass or it would not pass.In case the current is passing, we can say the value of output is 1 and it is 0 when no current is passing. Whether the value of the output would be 1 or 0, it depends upon the values of input variables( 1 and 0) which specify the state of the switches.In this example, the switches form the input variable because the value of output depends upon the state of these variables which shows that digital circuit can not produce same output voltage for different values of input voltage.
What is the output value if the input value is 4?
Anything you like - it depends on the function that relates the output to the input.
How does a change in the value of an input variable affect the value of an output variable?
The change in the input value is equalto the change in the output value.
What equation is used to calculate the dc output voltage for a given ac input voltage to a step-down transformer?
so far i knew, the transformers are used to seprate dc component from ac component of supply fed into primary winding of coil. still if dc output value of ac input has to be calculated then it is v2*2/sqrt(pi) where v2 is peak ac output voltage and is equal to v1*n2/n1 pi is a constant numerically equal to 3.14 thus the dc value is average value of output ac voltage -------------------sachin_the_rex@aol.in------------------------------
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 work resistor?
when a resistor is connected in a circuit it drop some voltage across it.when a circuit have large input voltage then by using a resistor of suitable value we get the desired voltage.

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 then output value if the input value is 5?
42
