\({\text{V  =  }}{{\text{V}}_{air}}{\text{  +  }}{{\text{V}}_{\ medium  }} = \,\,\frac{\sigma }{{{\varepsilon _0}}}\,\, \times \,\,\left( {d\,\, - \,\,t} \right)\,\, + \;\,\frac{\sigma }{{K{\varepsilon _0}}}\,\, \times \,\,t\,\,\)

\( \Rightarrow \,\,V\,\, = \,\,\frac{\sigma }{{{\varepsilon _0}}}\,\,\left( {d\,\, - \,\,t\,\, + \,\,\frac{t}{K}} \right)\,\, = \,\,\frac{Q}{{A{\varepsilon _0}}}\,\,\left( {d\,\, - \,\,t\,\, + \,\,\frac{t}{K}} \right)\)

માટે કેપેસીટન્સ \(C\,\, = \,\,\frac{Q}{V}\,\, = \,\,\frac{Q}{{\frac{Q}{{A{\varepsilon _0}}}\,\,\left( {d\,\, - \,\,t\,\, + \,\,\frac{t}{K}} \right)}}\,\, = \,\,\frac{{{\varepsilon _0}A}}{{\left( {d\,\, - \,\,t\,\, + \,\,\frac{t}{k}} \right)}}\,\, = \,\,\frac{{{\varepsilon _0}A}}{{d\,\, - \,\,t\,\,\left( {1\,\, - \,\,\frac{1}{k}} \right)}}\)
