Given, two capacitors of same capacities C .
In series, equivalent capacitance is given by

1

CS

=

1

C1

+

1

C2

=

1

C

+

1

C

=

2

C

CS=

C

2

In parallel, equivalent capacitance is given by
CP=C1+C2=C+C=2C
Ratio =

CP

CS

=

2C

( C 2 )

=

4

1

⇒CP:CS=4:1
Hence, Assertion is true.
In parallel, CP>C
In series,CS<C
So, in parallel, capacity is increased but in series, capacity is decreased.
Hence, Reason is also true, but it is not the correct explanation of Assertion.
