A shunt-wound DC generator is designed to provide a relatively constant terminal voltage across varying loads. This is achieved because the field winding is connected in parallel (shunt) with the armature, allowing the field current to remain more stable as load conditions change. However, it's important to note that while shunt generators can maintain a more constant voltage compared to other types, they may still experience some voltage drop under heavy loads. For applications requiring truly constant voltage, additional regulation methods may be employed.

What is the special properties of a diode?
in the negative biasing it gives the constant voltage irrespective of limited current.......the voltage it provides in the negative biasing is known as 'zener voltage' due to this property zener voltage is used as voltage regulator........voltage regulator is a circuit which gives constant output even the input is changing.

Is it possible to have the full load terminal voltage greater than the no load terminal voltage?
Not normally because the supply has a small resistance and very little reactance. Therefore the application of a load causes a voltage drop in the equivalent series resistance of the supply, so its voltage becomes slightly less. A typical supply resistance can be taken from my home, which has a 240 v 60 amp supply, and the resistance is 0.1 ohms, so that a 10 amp load gives a drop of 1 volt.
Why CC configuration is preferred for buffering?
it is noninverting and while it gives no voltage gain it gives a large current gain.
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.

Why the output voltage drop when the load current is increase?
As the load current increases the losses in the circuit increases (I2R loss) and speed of the generator decreases so the voltage falls a little. and this voltage fall can be adjusted by increasing the speed of the generator and Iron losses are taken as constant losses.

What is the name of the computer terminal which gives paper printout?
Hard copy terminal
What is a tool that gives electricity to other machines?
A generator.
Why CE configuration is most common?
CC gives only current gain, but no voltage gain; gives only limited power gainCB gives only voltage gain, but no current gain; gives only limited power gainCE gives both voltage and current gain; gives large power gain
What is capacitor polarized?
A polarized capacitor is one which has a polarity, positive on one terminal, negative on the other. This makes it superficially look like a battery. In use, the capacitor has its positive voltage always higher than that on the negative terminal, it matters that this is the case and this gives rise to the term polarized. This sort of capacitor is commonly found in power supply filters.
Does a generator produce direct current or alternating current?
A generator produces an alternating current, still it gives d.c. output because we use slip-rings at the terminals of actual output of generator.
Does voltage regulator increase or decrease the current input?
A DC voltage regulator gives a constant output voltage provided the input voltage is at least 1.5 v higher, up to a given limit. The input current is slightly more than the load current, because a small amoutn of current is needed for the voltage regulator circuit. Check the datasheet of the component which you are using to find the limits. 7805 IC can give upto 1A of current if there is adequete heatsinking.
Will high voltage gives strong magnetism?
yes
