Question

The minimum and maximum capacitances, which may be obtained by the combination of three capacitors each of capacitance 6$\mu$ F are

• A. 6$\mu$F and 18 $\mu$F
• B. 2 $\mu$F and 18$\mu$F
• C. 2 $\mu$F and 12 $\mu$F
• D. 6$\mu$ F and 12$\mu$ F

Answer 1

Answer: (B)

2 $\mu$F and 18$\mu$F

Answer 2

In series capacitance is minimum
$C_{min} =6/3 =2\mu F$
In parallel capacitance is maximum
$C_{max} =\left(6\times3\right) =18 \mu F$
