- Seven capacitors each of capacitance $2 \mu \mathrm{F}$ are connected in a configuration to obtain an effective capacitance $\frac{10}{11} \mu \mathrm{F}$. Which of the following combination will achieve the desired result?
Show Answer
Answer:
Correct Answer: 122.(a)
Solution:
Formula:
- In series, $C=\frac{C_{1} C_{2}}{C_{1}+C_{2}}$
$$ \therefore \quad C_{\text {net }}=\frac{(10)(1)}{10+1}=\frac{10}{11} \mu \mathrm{F} $$
