A 3.40 uF capacitor and a 3.60 uF capacitor are connected in series. (a) A charge of 4.90 mC is placed on each capacitor. What is the energy stored in the capacitors? (b) A 655 ? resistor is connected to the terminals of the capacitor combination, and a voltmeter with resistance 4.58 x 104 is connected across the resistor (Figure 1). What is the rate of change of the energy stored in the capacitors just after the connection is made? (c) How long after the connection is made has the energy stored in the capacitors decreased to 1/e of its initial value? (d) At the instant calculated in part (c), what is the rate of change of the energy stored in the capacitors? Find the value of t at which the stored energy has 1/e of the value you found in Part G.
