Questions  

You are given 8 metallic plates, Any two plates arc to be separated from each other so that capacitance of the capacitor formed by them is 1 μF. What is the maximum capacitance one can obtain with them

a
2 μF
b
4 μF
c
6 μF
d
7 μF

detailed solution

Correct option is D

The plates can be connected as shown in fig. to give maximum capacitance. It is obvious from the figure that the combination is equivalent to 7 capacitors in parallel. As the capacitance of each capacitor is 1 μF and hence the total capacitance is 7 μF.
