Question

Two capacitors of capacitance C each are connected in series. If one of them is filled with dielectric substance (k = 6) and other is filled with dielectric substance (k = 3). The effective capacitance of the combination will be
​

Answer 1

Answer:

When capacitance filled with dielectric , the capacitance becomes C

′

=kC

As they are in series so effective capacitance is C

ef

=

C+C

′

CC

′

=

C+kC

C(kC)

=

1+k

kC
