The parallel combination of two air filled
parallel plate capacitors of capacitance C and
nC is connected to a battery of voltage, V. When
the capacitors are fully charged, the battery is
removed and after that a dielectric material of
dielectric constant K is placed between the two
plates of the first capacitor. The new potential
difference of the combined system is :-
