Question

Condensers of capacities $2\mu F$ and $3\mu F$ are connected in series and a condenser of capacity $1\mu F$ is connected in parallel with them. The resultant capacity is:

• A. $0.5\mu F$
• B. $1.1\mu F$
• C. $22\mu F$
• D. $2.2\mu F$

Answer 1

Answer: (D)

$2.2\mu F$

$\frac{6}{5}+1=\frac{11}{5}=2.2\mu F$.
