Chapter 25, Problem 25.73P
CP Consider the circuit shown in Fig. P25.73. The emf source has negligible internal resistance. The resistors have resistances R1 = 6.00 Ω and R2 = 4.00 Ω. The capacitor has capacitance C = 9.00 µF. When the capacitor is fully charged, the magnitude of the charge on its plates is Q = 36.0 µC. Calculate the emf ε.

The circuit in Figure P27.41 contains two resistors, R1 = 2.00 kΩ and R2 = 3.00 kΩ, and two capacitors, C1 = 2.00 μF and C2 = 3.00 μF, connected to a battery with emf ε = 120 V. If there are no charges on the capacitors before switch S is closed, determine the charges on capacitors (a) C1 and (b) C2 as functions of time, after the switch is closed.
3. The circuit in Figure P28.75 contains two resistors,
R1 = 2.00 k2 and R2 = 3.00 kN, and two capacitors,
C = 2.00 µF and C2 = 3.00 µF, connected to a battery with
emf ɛ = 120 V. No charge is on either capacitor before
switch S is closed. Determine the charges q1 and q2 on
capacitors C1 and C2, respectively, after the switch is closed.
(Suggestion: First reconstruct the circuit so that it becomes a
simple RC circuit containing a single resistor and single
capacitor in series, connected to the battery, and then deter-
mine the total charge qstored in the equivalent circuit.)
