Unformatted text preview: Problem # 11 In the above circuit, the switch closes at t = 0. The source is a steady DC voltage source equal to 50 volts. The current through the inductor at t = (0-) is 0 and the voltage across the capacitor at t = (0- ) is 0. 1. Use KCL to write a differential equation for the voltage across the capacitor. Put this equation in standard form. 2. What is the form of the particular solution ? 3. What is the form for the complementary solution. State your reason for choosing this form of complementary solution.

### What students are saying

• 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.
