The equivalent capacitance of the combination shown in the figure is:

The equivalent capacitance of the combination shown in the figure is:

Options

A $3C$
B $\dfrac{C}{2}$
C $2C$
D $3C / 2$

Correct answer

C. $2C$

Step-by-step solution

The equivalent capacitance of the combination shown in the figure is:

Redrawing the circuit between $A \text{ and } B$ ,

The equivalent capacitance of the combination shown in the figure is:

Capacitor $3$ can be eliminated

Capacitor $1$ & $2$ are in parallel.

${C}_{AB} = {C}_{1} + {C}_{2}$

$= C + C$

$= 2C$
