A

the copper plate capacitor has a greater capacitance the iron one

B

both the capacitors will have same capacitance only in uncharged state

C

both the capacitors will have equal capacitance only when they are equally charged

D

both the capacitors will always have same capacitance

Text Solution

Verified by Experts

The correct Answer is:

A parallel plate capacitor is charged. If the plates are pulled apart

Two identical parallel-plate air capacitors are connected in one case in parallel and in the other in series. In each case the plates of one capacitor are brought closer together by a distance a and the plates of the other are moved apart by the same distance a. How will the total capacitance of each system change as a result of such manipulations ?

Two parallel plate capacitors are found to store the same amount of charge when connected to the same battery one by one. Their plate areas are 300 cm^(2) and 700cm^(2) . Separation between the plates of first capacitor is 2 mm. Calculate separation between the plates of second capacitor.

Two parallel plate capacitors X and Y have the same area of the plates and same separation between them, are connected in series to a battery of 15 V. X has air between the plates while Y contains a dielectric of constant k = 2. Calculate the potential difference between the plates of X and Y.

Two parallel plate capacitors X and Y, have the same area of plates and same separation between plates. X has air and Y with dielectric of constant 2 , between its plates. They are connected in series to a battery of 12 V. The ratio of electrostatic energy stored in X and Y is-
