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 30μC

D) Total charge flown from A to D is -30μC

Show Answer

Answer:

Correct Answer: C

Solution:

[c] V=Q1+Q2C1+C2=0

Final potential difference = zero Final charge = zero Charge flow 30μC from A to D
