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 $
