# If the area of parallel plates shown in the figure is ‘A’ and they are placed at distance ‘d’ apart form each other, then find the equivalent capacitance between A and B. (The two outer plates are connected with a conductivity wire)

$(B) \large\frac{A \in_0}{d} \bigg[ \large\frac{k_1k_2+k_1+k_2}{(k_1+k_2)}\bigg]$
