**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. KCL 4.0 +11. driz‘fxzvso 1... tjwdkg—io 1’ lg— P ,_———- >0 No 5.9. @ a K 0a” 0 saw: rm! 0161’ \
