Question

If three capacitors each of capacity $1\mu F$ are connected in such a way that the resultant capacity is $1.5\mu F$, then

• A. All the three are connected in series
• B. All the three are connected in parallel
• C. Two of them are in parallel and then connected in series to the third
• D. Two of them are in series and then connected in parallel to the third

Answer 1

Answer: (D)

The circuit can be drawn as follows

$\Rightarrow$ Equivalent capacitance
$C_{eq}=\frac{1}{2}+1=\frac{3}{2}\mu F$
