EE 350 PROBLEM SET 1 DUE: 5 SEP 2007 Reading assignment: Lathi Chapter 1 and Background, Sections B.2 and B.3, and the MATLAB primer (available on the EE 350 web page). Recitation sections will meet the week of August 27. Problems 1 and 2 are a review of material covered in EE 210 and require you to obtain an ordinary differential equation and initial conditions for a simple circuit. Problem 1: (25 points) Consider the RC circuit in Figure 1. The independent voltage source has constant amplitude V s and, prior to the switch closing at time t = 0, the voltage v ( t ) across the capacitor C is zero. + - + - C R V s t = 0 v(t) i(t) Figure 1: 1. (4 points) What is the voltage v (0 + ) across the capacitor just after the switch is closed ? Why ? 2. (4 points) Find the current i (0 + ) through the capacitor just after the switch is closed. 3. (4 points) Find the voltage v ( ) after the switch has been closed for a very long time. 4. (4 points) Find the current i ( ) after the switch has been closed for a very long time.
