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.

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.
it is noninverting and while it gives no voltage gain it gives a large current gain.
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.

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.

A generator.
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
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.
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.
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.
yes
Watson gives it to you when you turn of the mauvile city generator
