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 \[\frac{12}{C}=\frac{1}{4}+\frac{1}{4}=\frac{1}{2}\] 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.
