779 The capacitors are initially uncharged and switch S is open. What is the potential difference between a and b? What is the potential at point b, relative to ground (g), after switch S is closed? How much charge flowed through the switch when it was closed? (See note at the beginning of Problem 787) a) b) c) 6uF2 3μF S +200 V HHH V-0 3μF 6μF Hint for LM 779: After the switch is closed, the two upper capacitors are in parallel with each other, and the two lower capacitors are in parallel with each other.

C2 The next two questions refer to the following figure. The switch is initially open and both capacitors are initially uncharged. All resistors have the same value R, and both capacitors have the same value C. R2 R3 bat R1 ww (f) 1 pt. Immediately after the switch is closed, which resistor has the most current through it? (i) R1 (ii) R2 (iii) R3 (iv) Rị and R2 (v) R2 and R3 (vi) All have the same current (g) 1 pt. A long time after the switch is closed, which resistor has the most current through it? (i) R1 (ii) R2 (iii) R3 (iv) R1 and R2 (v) R2 and R3 (vi) None have current
