WHEN 2 CAPACITORS OF CAPACITANCE C1 AND C2 ARE CONNECTED IN SERIES THE NET CAPACITANCE IS 12/7 MICROFARADAY AND WHEN CONNECTED IN PARALLEL 7 MICROFARADAY,FIND C1 AND C2
We have ,
         In series connection the effective capacitance = C1C2/(C1+C2)
                                                                                   =12/7Micro farad
 In parallel connection the effective capacitance = C1+C2  =7 Microfarad    ....(1)
                              On substitution we get,
                                                 C1C2/7 =12/7
                                 C1C2 =12   ......(2)
From equation (1) &(2) we get,
                             C1 =3Microfarad
                             C2=4Microfarad
