Question
The circuit in the figure below contains two resistors, R, = 1.9 kN and R, = 2.7 k2, and two capacitors, C, = 1.7 µF and C, = 3.4 µF, connected to a battery
with emf E = 140 V. If there are no charges on the capacitors before switch S is closed, determine the charges q, and q, on capacitors C, and C,,
respectively, as functions of time, after the switch is closed. Hint: 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 determine the total charged q stored in the circuit. (Use the given values for R,, R2,
C,, Ca, and E. Use the following as necessary: t. Do not include any units in your response.)
