A) \[600\,\mu C;\,150\,V\]
B) \[300\,\mu C;\,75\,V\]
C) \[800\,\mu C;\,200V\]
D) \[580\,\mu C;\,145V\]
Correct Answer: D
Solution :
Total capacitance\[\frac{1}{C}=\frac{1}{20}+\frac{1}{8}+\frac{1}{12}\] \[\Rightarrow \] \[C=\frac{120}{31}\mu F\] Total charge \[Q=CV=\frac{120}{31}\times 300=1161\mu C\] Charge through \[4\mu F\] condenser \[=\frac{1161}{2}=500\mu C\] and potential difference across it \[=\frac{580}{4}=145\,\,V\]You need to login to perform this action.
