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.

How do rectifier circuits stabilize the output voltage when the input voltage is subject to fluctuations?

Rectifiers don't "stabilize the output voltage" of rectifier circuits when input voltage fluctuates. The rectifiers just rectify the input, and the output will fluctuate as the input does. Another form of "conditioning" of the rectified output is needed to address the issue of fluctuations. And we use the term regulation to talk about the effect of "stabilizing" an output voltage. Through regulation, the output will be resistant to changes in voltage when changes in the input voltage occur.

What is voltage gain?

Voltage gain is the ratio of the output voltage of an amplifier to its input voltage.

Why clipping happen for op-amp?

Clipping occurs in the voltage waveform when the input voltage, multiplied by the voltage gain of the op-amp circuit, exceeds the op-amp supply voltage as limited by the output network. The supply voltage and output network, limits the maximum voltage that can be achieved at the output. The op-amp behaves normally within its range of maximum voltage output, and then it is clipped when it reaches the maximum voltage of the circuit.

What are the output voltage and current of a transformer determined by?

The secondary (output) voltage is determined by the primary voltage and the turns ratio of the transformer. The secondary current is determined by the secondary voltage and the load resistance.

What causes increase of the output of a generator that should be 220 volt to 400 volt?

It sounds like the field voltage potentiometer is not working or has been turned up. Try turning it down and see if the output voltage goes down with it. If it doesn't then the voltage regulator is not working as the field voltage is regulated from the regulator.

What is an 7805 regulator?

7805is a voltage regulator integrated circuit. It is a member of 78xx series of fixed linear voltage regulator ICs. The voltage source in a circuit may have fluctuations and would not give the fixed voltage output. The voltage regulator IC maintains the output voltage at a constant value. The xx in 78xx indicates the fixed output voltage it is designed to provide. 7805 provides +5V regulated power supply. Capacitors of suitable values can be connected at input and output pins depending upon the respective voltage levels.Pin Diagram:Pin Description:Pin NoFunctionName1Input voltage (5V-18V)Input2Ground (0V)Ground3Regulated output; 5V (4.8V-5.2V)Output

What is a regulated variable direct current?

Voltage regulators that are adjustable are common, for example the LM338, which can pass up to 5 amps with a suitable heat sink, and the output voltage is set by two external resistors connected to the regulator. A variable resistor can be used to make the output voltage directly adjustable.

The term voltage regulated means that the?

voltage output of a device or system remains constant despite variations in input voltage or load. This ensures stability and reliability in electrical circuits.

What is operation of IC 7806?

this is the voltage regulator IC which gives you +12 volts. after the capaciter it is being used in power supply.In 7812 , the 78 denotes (+ve) while 79 denotes (-ve) i.e.7912 provide you -12 volts. thelast two figure shows the output voltage.

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 happen to the output voltage of the DC power supply if turn ratio in the secondary winding are reduce?

For linear supplies, the straightforward answer is: THE VOLTAGE GOES DOWN. For regulated unipolar switching supplies (all bets are off), it is likely that your pulse width will increase until you are at the regulated voltage set at the chip. Not all DC supplies behave the same way.

What is DC to DC conversion?

A DC to DC converter is a type of switching regulated powersupply whose input is a DC voltage, it then switches that rapidly to make AC, which is applied to the primary of a transformer, the transformer then either steps up or down the voltage as desired, the AC from the secondary is then rectified and filtered to provide the output DC voltage. Regulation circuitry measures the output DC voltage, continuously adjusting the switching circuits on the input to keep the output constant.Most switching regulated powersupplies are DC to DC converters with a simple unregulated rectifier and filter to convert the input AC to DC. Usually it is called a powersupply when it provides more than one output DC voltage or if its input is AC; whereas it is called a converter only if it provides just one output DC voltage and its input is DC. But most of the circuitry is the same in both cases.

Why is the output voltage of an alternator regulated?

To limit the rate at which the charge is put into the battery in order to prevent overheating, boil-out of the water in the acid electrolyte, and eventually ruining the battery.
