Vedclass · Answer

(B) In the given circuit,the two capacitors on the right side are connected in parallel,and their combination is in series with the capacitor on the left. However,looking at the circuit diagram,the vertical capacitor is connected across the nodes that are effectively short-circuited by the wire on the right. Alternatively,by analyzing the potential difference,the vertical capacitor is connected between two points that are at the same potential due to the parallel wire connection. Thus,the vertical capacitor is short-circuited and does not contribute to the equivalent capacitance. The remaining two capacitors are connected in parallel to the input terminals. Therefore,the equivalent capacitance is $C_{eq} = C + C = 2C$.

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