Question

In the circuit diagram shown in the adjoining figure, the resultant capacitance between `P` and `Q` is

A. `47 muF`
B. `3 muF`
C. `60 muF`
D. `10 muF`

Answer 1

Correct Answer - B
The given circuit can be draws as

where `C = (3 + 2) muF = 5 muF`
`(1)/(C_(PQ)) = (1)/(5) +(1)/(20) + (1)/(12) = (20)/(60) = (1)/(3)`
`rArr C_(pQ) = 3 muF`
