Question

The capacities of the three capacitors are in ratio 1 : 2 : 3. Their equivalent capacity when connected in parallel is

\frac{60}{11} μ F

more than when they are connected in series. The individual capacities of capacitors in

μ F

are?

Options:

A . 4, 6, 7

B . 1, 2, 3

C . 2, 3, 4

D . 1, 3, 6

Answer: Option B
:
B

C_{p} = x + 2 x + 3 x = 6 x - - - - - (1)

\frac{1}{C_{s}} = \frac{1}{x} + \frac{1}{2 x} + \frac{1}{3 x} = \frac{11}{6 x}

C_{s} = \frac{6 x}{11} - - - - - - - - (2)

C_{p} = \frac{60}{11} + C s

6 x = \frac{60}{11} + \frac{6 x}{11}

66 x - 6 x = 60

60 x = 60 x = 1 μ F

C_{1} = 1 μ F; C_{2} = 2 μ F; C_{3} = 3 μ F
