The equivalent capacitance of the combination between A and B in the given figure is `4 mu F ` .
Calculate capacitance of the capacitor C.

Explanation

As capacitance of series combination of two capacitors of capacity `20 mu F ` and C are `4 mu F ` , hence , `C_(eq) = 4 mu F = (20 mu F xx C)/((20 mu F xx C)) implies C = 5 mu F `
