In the figure, the equivalent capacitance between A and B is
A) 3.75\[\mu F\]
B) 5.25\[\mu F\]
C) 6.5\[\mu F\]
D) 10.5\[\mu F\]
Correct Answer:
A
Solution :
The circuit can be simplified as shown. It is a balanced Wheatstone bridge. \[\Rightarrow \] \[{{C}_{AB}}=\frac{5\times 3}{5+3}+\frac{5\times 3}{5+3}\] \[\Rightarrow \] \[{{C}_{AB}}=2\times \frac{15}{8}=\frac{30}{8}=3.75\,\mu F\]
