$$ \text { In the figure below, the capacitance of each capacitor is } 3 \mu \mathrm{F} \text {. The effective capacitance between } \mathrm{A} \text { and } \mathrm{B} \text { is : } $$

• A

  $\frac{3}{4} \mu \mathrm{F}$
• B

  $3 \mu \mathrm{F}$
• C

  $6 \mu \mathrm{F}$
• Correct answer
  D

  $5 \mu \mathrm{F}$

Solution

Hints:
$$ \frac{2 \mathrm{C}}{3}+\mathrm{C}=2+3=5 \mu \mathrm{F} $$

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