You connect a battery, a resistor, and a capacitor as shown in Figure 4, in that e = 36.0 V, C = 5.0 uF and R = 120 Ohms C. The switch S is closed at t = 0. (a) When the voltage across the capacitor is 8.00 V, what is the magnitude of the current in the circuit? (b) At what time t after the switch is closed the voltage across the capacitor is equal to 8.00 V? (c) When the voltage across the capacitor equals 8.00 V, at what speed is energy being stored in the capacitor?

An initially uncharged capacitor with a capacitance of C = 5.00 µF is connected in series with a resistor with a resistance of R = 4.5 k. If this series combination of circuit elements is attached to an ideal battery with an emf of Ɛ = 450 V by means of a switch S that is closed at time t = 0, then answer the following questions. (a) What is the time constant of this circuit? (b) How long will it take for the capacitor to reach 75% of its final charge? (c) What is the final charge on the capacitor?
