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