A) 2\[\mu \]F
B) 2\[\mu \]F
C) 8\[\mu \]F
D) 4\[\mu \]F
Correct Answer: D
Solution :
From figure, the effective capacitance of \[{{C}_{1}},{{C}_{2}}\] and \[{{C}_{3}}\] is given by \[\frac{1}{C}=\frac{1}{4}+\frac{1}{2+2}=\frac{1}{2}\] \[\Rightarrow \] \[C=2\mu F\] Effective capacitance of \[{{C}_{4}}\] and \[{{C}_{5}}\] is \[\frac{1}{C}=\frac{1}{4}+\frac{1}{4}=\frac{1}{2}\] or \[C=2\mu F\] Now effective capacitance between A and B \[C=C+C\] \[C=(2+2)\mu F=4\mu F\]You need to login to perform this action.
