question_answer

Three capacitors of equal capacity C are connected as shown in figure, the equivalent capacitance of the combination between A and B is C

A)  C                                

B)  2 C

C)  \[\frac{C}{2}\]                         

D)  None of these

Correct Answer: B

Solution :

Here 3rd capacitor is ineffective as potential difference across 3rd capacitor is zero, so equivalent figure will be \[\therefore \] Equivalent capacitance between A and B \[=C+C=2C\]
