Explanation:
★ CAPACITANCE
★ GIVEN ;
» Thickness is 1 / 4 th of the Plate seperation
» t = d / 4
★ New Capacitance = ???
____________________________________
We know that ;
★ C = Ë × A / [ (d - t ) + t / K ]
★ C = Ë × A / [ d - d / 4 ] + d / 4K ]
★ C = Ë × A / [ 3d / 4 ] + d / 4K ]
★ C = Ë × A / [ 3d / 4 + d / 4 ( 1 / K ) ]
★ C = Ë × A [ d × 1 / K ]
★ C = Ë × A × K / d ★
