Q) The distance between the plates of a capacitor is d. A metal plate of thickness d/2 is placed between the plates; what will be the effect on the capacitance?
Q) Is there any material which when inserted b/w the plates of a capacitor reduces its capacitance?
Q) The plates of a capacitor are connected by a voltmeter. If the plates are moved further apart what will be the effect on the reading of voltmeter?
Q) Sketch graph to show how the capacitance of a capacitor varies with charge given to it.
Q) A charged air capacitor has energy stored U. What will be the energy stored air is replaced by a dielectric of constant "K" ; CHARGE remaining same.
Q) Why does the polarization of dielectric reduce the electric field inside it?
Q) What happens to the energy stored in a capacitor when the plates of charged capacitor are moved farther after -------a) connecting , b) disconnecting the battery.
Q) Two capacitor C-1 and C-2 are connected in parallel. A charge 'q' is given to this combination.What will be the p.d. across each capacitor?
Q) Two spheres of Cu of same radii--- one hollow and other solid are charged to same potential. Which possesses more charge?

Respected Alka mam, you exactly did not know the way of teaching.You teach as if you are teaching spark batch students who have higher aptitude.Weak students find it difficult to understand your way of teaching.You teach class as if 1 student understands your concept then you think that the whole class understands concepts i.e. why students prefer tuition rather than school. But think about those students who can't afford tuition. This gradually leads to the weakening of concepts among the students.So mam this is a kind request from my-side & my other classmates to improve your way of teaching when you come after your leave.
Thanking You
[a concerned student of your ex-class]
