Question
A gang capacitor is formed by interlocking a number of plates as shown in figure. The distance between the consecutive plates is 0.885 cm and the overlapping area of the plates is 
The capacity of the unit is
- 1.06 pF
- 4 pF
- 6.36 pF
- 12.72 pF
The correct answer is: 4 pF
The given arrangement of nine plates is equivalent to the parallel combination of 8 capacitors.
The capacity of each capacitor,
Hence, the capacity of 8 capacitors
