Electrostatics Question 650
Question: The capacities and connection of. five capacitors are . The potential difference between the points A and B is 60 volts. Then the equivalent capacity between A and B and the charge on $ 5\mu F $ capacitance will be respectively
Options:
A) $ 44\mu F;300\mu C $
B) $ 16\mu F;150\mu C $
C) $ 15\mu F;200\mu C $
D) $ 4\mu F;50\mu C $
Show Answer
Answer:
Correct Answer: D
Solution:
[d] The given circuit can be redrawn as follows Equivalent capacitance of the circuit $ C _{AB}=4\mu F $ Charge given by the battery
$ Q=C _{eq}V=4\times 60=240\mu C $
Charge in $ 5\mu F $
capacitor $ Q’=\frac{5}{(10+5+9)}\times 240=50\mu c $
