A gang capacitor is formed by inter locking a number of plates as shown in the figure. The distance between the consecutive plates is 0.885cm and the overlapping area of the plates is 5cm2. The capacity of the unit is
(a) 1.06 pF
(b) 4 pF
(c) 6.36 pF
(d) 12.72 pF
Correct option (b)
Explanation:
The given arrangement of nine plates is equivalent to the parallel combination of 8 capacitors. The capacity of each capacitor,
