Combination of Capacitors

Two equal capacitors are first connected in series and then in parallel. The ratio of the equivalent capacities in the two cases will be:

Show answer and solution

Answer: (d)

  1. Series: Cs=C2C_s = \frac{C}{2}. Parallel: Cp=2CC_p = 2C.
  2. CsCp=C/22C=14\frac{C_s}{C_p} = \frac{C/2}{2C} = \frac{1}{4}
  3. So the answer is (d) 1:41 : 4.
