Question

Three equal condensers of capacity $C$ each are connected to form a triangle as shown above. The effective capacity across any side is :

• A. $C/3$
• B. $C/2$
• C. $3C/2$
• D. $3C$

Answer 1

Answer: (C)

Two capacitor are in series ,

$\frac{1}{Ceq}=\frac{1}{C}+\frac{1}{C}⟹Ceq=\frac{C}{2}$

Now this capacitor is in parallel with the C ,

$C_e=C+\frac{C}{2}{C}_e=\frac{3C}{2}$
