. If we have a parallel plate capacitor of plate area 'A'
and plate separatoin t and having a capacity C and a
metallic plate r of area A and of negligible thickness is
introduced in the capacitor at a distance from either of
the two plates as shown in the given figure then the
capacity of the capacitor will become
a.) b.) C c.) 2C d.) 4C

Answer Posted / monu
Can u tell me how???
What i am thinking is C=EA/D E : Permeability
So when a metalic film is introduced the it ll make two capacitors half of thickness connected in series.
Ceq = C1 + C2 where C1 = C2 = EA/(D/2)= 2C
So Ceq = 2c||2c = C
