Question
Plz tell me in detail that how the capacitance of capacitor is increased by using dielectric

Answer
For technical discussion go to section 27.4 in the following link:

http://teacher.nsrl.rochester.edu/phy122/Lecture_Notes/Chapter27/chapter27.html

Another explanation more easily understood is:

http://farside.ph.utexas.edu/teaching/302l/lectures/node45.html

And, one more:

If you don't like reading the above explanations, you can think of the dielectric merely allowing some charge to be built up within the space between the plates.  It acts to enhance the virtual capacitance.

Hope this helps.
