- A capacitor of capacitance C and resistors or resistance R are connected in series as shown in the picture below. The switch is initially open. Which of the following statements is true after the switch has been closed for a very long time? R O AVc = € AVR = €Find the total resistance RTThe circuit in the figure below contains two resistors, R, 1.9 kl and R₂2.8 kf, and two capacitors, C₂ -1.9 f and C₂-3.1 uf, 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 a, and dy on capacitors C, and C₂, respectively, as functions of time, after the switch is closed. Hint: First reconstruct th 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 a stored in the circult.
