Question
Two capacitors of 2.0 and 4.0 mF are
connected in parallel. This group is
connected in series with a 3.0 mF capacitor
across an 800-V line. Find the potential
difference across each capacitor.
A capacitor (10.0 uF) is connected to a
power supply and charged to 120 V, then
disconnected to the power supply. Switch S
is open.
A) What is the charge Q[0] on 10.0-µF
capacitor.
B) What is the energy stored in the 10.0-uF
capacitor?
C) A 5.0-µF is initially uncharged. We close
switch S. After charge no longer flows, what
is the potential difference across each
capacitor?
D) What is the final energy of the system?
V120 V
C -10.0 uF
C: 5.0 uF
