In figure, four parallel plates of equal area A and spacing d are arranged, then effective capacitance between a and b is
A) \[\frac{{{\varepsilon }_{0}}A}{d}\]
B)
C)
D)
Correct Answer: C
Solution :
The given arrangement is equivalent to the parallel combination of three identical capacitors, pence, equivalent capacitance \[=3C=\frac{3{{\varepsilon }_{0}}A}{d}\]
