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 identical parallel plate capacitors of same dimensions joined in series are connected to a constant voltage source. When one of the plates of one capacitor are brought closer to the other plate :

Two identical parallel plate air capacitors are connected in series to a battery of emf V. If one of the capacitor is completely filled with dielectric material of constant K, then potential difference of the other capacitor will become

Two parallel plate air capacitors are construted, one by a pair of iron plates and the second by a pair of copper plates of same area and same spacings. Then

How will the voltage (V) between the two plates of a parallel plate capacitor depend on the distance (d) between the plates, if the charge on the capacitor remains the same?

Two identical parallel plate capacitors are connected in series and then joined in series will a batter of 100 V . A slab of dielectric constant K=3 is inserted between the plates of the first capacitor. Then, the potential difference across the capacitor will be, respectively.

Two idential capacitors are joined in parallel, charged to a potential V and then separated and then connected in series i.e. the positive plate of one is connected to negative of the other

Two similar parallel plate capacitors each of capaciti C_0 are connected in series The combination is connected with a voltage source of V_0 . Now, seperation between the plates of one capacitor is increased by a distance d and the separation between the plates of another capacitor is decreased by the distance d/2 . The distance between the plates of each capacitor was d before the chane in sepration. Then select the correct choice.

A very thin plate of metal is placed exactly in the middle of the two plates of a parallel plate capacitor. What will be the effect on the capacitance of the system?

Two parallel plate capacitors, each of capacitance 40 muF, are connected is series. The space between the plates of one capacitor is filled with a dielectric material of dielectric constant K =4. Find the equivalent capacitacne of the system.
