Capacitors 1, 2 and 3, have capacitances equal to 2.00 μF,
4.00 μF, and 6.00 μF, respectively. The capacitors are connected in parallel, and
the parallel combination is connected across the terminals of a 200-V source. The
capacitors are then disconnected from both the voltage source and each other, and
are connected to three switches as shown in Figure 24-42. (a) What is the
potential difference across each capacitor when switches S1 and S2 are closed but
switch S3 remains open? (b) After switch S3 is closed, what is the final charge on
the leftmost plate of each capacitor? (c) Give the final potential difference across
each capacitor after switch S3 is closed.
For part b, is would the capacitors be connected in series? Also if they're in series would the sum of all 3 voltages be 0 b/c no voltage source is connected?
