If each capacitor has capacitance

C

, then equivalent capacitance between

A

and

B

If each capacitor has capacitance C , then equivalent capacitance between A and B is

Options

A $\dfrac{4C}{3}$
B $\dfrac{8C}{3}$
C $12C$
D $\dfrac{5C}{12}$

Correct answer

B. $\dfrac{8C}{3}$

Step-by-step solution

Mark equipotential points and redraw the circuit in order to identify series and parallel combinations.

If each capacitor has capacitance C , then equivalent capacitance between A and B is

{C}_{eq} . = 4 \times \dfrac{2C \times C}{2C + C} = \dfrac{4 \times 2C}{3} = \dfrac{8C}{3}
