Question

Cs and Cp are equivalent capacitances of
three capacitors each of capacitance C in
series and parallel combinations
respectively. The ratio Cp/Cs.
Options:​

Answer 1

Explanation:

Let the capacitance of each capacitor be C.

Effective capacitance in series connection

Cs1

= C1 + C1 +C1

∴ Cs = 3C

Effective capacitance in parallel connection Cp =C+C+C

∴ C p =3C

Thus ratio of effective capacitance

Cp

C s = 3C

C/3⟹

Cs:Cp=1:9
