Question

The capacities of the three capacitors are in ratio 1 : 2 : 3. Their equivalent capacity when connected in parallel is 6011μF more than when they are connected in series.  The individual capacities of capacitors in μF are?


Your Answer
A
4, 6, 7
Correct Answer
B
1, 2, 3
Your Answer
C
2, 3, 4
Your Answer
D
1, 3, 6

Solution

The correct option is B 1, 2, 3
Cp=x+2x+3x=6x    (1)
1Cs=1x+12x+13x=116x
Cs=6x11       (2)
Cp=6011+Cs
6x=6011+6x11
66x6x=60
60x=60      x=1μF
C1=1μF;C2=2μF;C3=3μF
