Two equal capacitances are connected first in series and then in parallel. The ratio of the effective series capacitance to the effective parallel capacitance is

Assuming the two equal capacitance has 2uf each then
the effective capacitance in series is
1/c=1/2+1/2
=1+1\2
=2/2=1uf

Effective capacitance in parallel
Cp=C1+C2
=2+2
=4uf
The ratio of effective capacitance in series and parrallel
series=1
parrallel=4
Cs/Cp=1/4
=0.25

Let the capacitance be C
since they are equal

Effective capacitance in series is
C×C/C+C
= C²/2C

Effective capacitance in parallel is
C+C
=2C

Cs/Cp = (C²/2C)×1/2C
Cs/Cp = 1/4
= 0.25
