Solve the all parts of following question:
Question: Three capacitors having capacitances of 8.4 uF, 8.9 uF, and 4.9 uF are connected in series across a 33-V potential difference.
Part A: What is the charge on the 4.9 uF capacitor?
Q3= _____C
Part B: What is the total energy stored in all three capacitors?
U= ____J
Part C: The capacitors are disconnected from the potential difference without allowing them to discharge. They are then reconnected in parallel with each other, with the positively charged plates connected together. What is the voltage across each capacitor in the parallel combination?
V=____
Part D: What is the total energy now stored in the capacitors?
U= ____J
Please show all work and steps to determine the total energy stored in all three capacitors.
