The effective capacitance between points $A$ and $B$ shown in the figure is

• A

  $10 \mu \mathrm{F}$
• Correct answer
  B

  $15 \mu \mathrm{F}$
• C

  $20 \mu \mathrm{F}$
• D

  $25 \mu \mathrm{F}$

Solution

The effective capacitance between point A and B is $$ \mathrm{C}_{\text {eq }}=10+5=15 \mu \mathrm{F} $$ Distance, $\mathrm{d}=3 \mathrm{~m} \lambda$

Hence, the correct answer is option: 'B'.
