Electrostatics Question 653
Question: Initial status of capacitor and their connection is shown. Which of the following is incorrect about this circuit?
Options:
A) Final charge on each capacitor will be zero
B) Final total electrical energy of the capacitors will be zero
C) Total charge flown from A to D is $ 30\mu C $
D) Total charge flown from A to D is -$ 30\mu C $
Show Answer
Answer:
Correct Answer: C
Solution:
[c] $ V=\frac{Q _{1}+Q _{2}}{C _{1}+C _{2}}=0 $
Final potential difference = zero Final charge = zero Charge flow $ 30\mu C $ from A to D
