Question

Two capacitors of capacitance C are connected in series. If one of them is filled with dielectric substance k, the effective capacitance is

Answer 1

Answer:

When capacitance filled with dielectric , the capacitance becomes C ′  = kC

As they are in series so effective capacitance is

C  ef = CC'/ C +C'

       = C(kC)/ C +kC

       = kC / 1 + k is the answer
