 CAPACITANCE  MCQ Short QUESTIONS ANSWERS Part 2

Any conducting object connected to earth is said to be grounded. Explain :

The earth is an electron source or sinks and is arbitrarily said to be zero potential. A conducting body connected to earth is also at zero potential or ground potential. Alternatively, the capacitance of the earth is so large that removal of electrons from it or supply of electrons to it makes no difference either in the charge or potential of earth.

• The two charged conductors are touched mutually and then separated. What will be the charge on them?

              The charge on them will be divided in the ratio of their capacitances. We know that q= CV.

              When the charged conductors touch, they acquire the same potential. Hence q∞ C 

• The plates of a charged capacitor are connected to a voltmeter. If the plates of the capacitor are separated further, what will be the effect on the reading of the voltmeter?

                             V= q/C and C= €0 A/d

            As the capacitor plates are separated, C decreases. Since charge on the plates remains the  

            same, value of V increases. Hence, the reading of the voltmeter will increase.
