Capacitance

Question

Three capacitors each of value 3 μF are available. The minimum and maximum capacitance which may be obtained by use of these are :

Easy

A

1 μF and 9 μF
B

3 μF and 9 μF
C

3 μF and 6 μF
D

1 μF and 6 μF

Solution

${(\frac{1}{C_{1}} + \frac{1}{C_{2}} + \frac{1}{C_{3}})}^{- 1} \leq C_{eq} \leq C_{1} + C_{2} + C_{3}$
${(\frac{1}{3} + \frac{1}{3} + \frac{1}{3})}^{- 1} \leq C_{eq} \leq 3 + 3 + 3$
$\Rightarrow 1 μF \leq C_{eq} \leq 9 μF$
