(c) The current has its largest value when so The graphs are of the same form as in Figures 19.33a and b in the textbook. Reflect: The maximum charge on the capacitor does not depend on the resistance. The initial current is the same as the current produced when the resistor alone is connected to the battery. 19.68. Set Up: The time constant is so and Solve: (a) gives Three time constants are required. (b) so 19.69. Set Up: After a long time the current has dropped to zero, there is no potential drop across the resistor and the full battery voltage is applied to the capacitor network. Just after the switch is closed the charge and voltage across each capacitor is zero and the battery voltage equals the voltage drop across the resistor. The time constant is where C is the equivalent capacitance of the network. Solve: (a) The 20.0 pF, 30.0 pF and 40.0 pF capacitors are in series and their equivalent capacitance is given by After a long time the voltage across the 10.0 pF capacitor is 50.0 V. The charge on this capacitor is

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
