SP212‐Spring‐2016 CH‐27‐C Assignment First do the following Wiley‐Plus assignment: Assignment #27c After completing the Wiley‐Plus, in your homework notebook, complete the following problems: CH27 Question # 12 CH27 Problems # 49 and 59. To check your work, the answers to the odd problems are in the back of the book. The answers to the even problems are: None assigned Homework Then complete the attached worksheets: (Note: the above problems were designed to ensure you have the skills to solve the worksheet problems. It is imperative to your learning of the problem solving technique to do the above problems BEFORE attempting the worksheet problems. You are graded on both! Homework notebooks are graded.) CH‐27‐C‐1: For each of the equations below, 1) State what each term is in your own words … 2) What the units of each term are… 3) What is the general use of that equation in your own words? A.

) CH‐27‐C‐2: At time t = 0, the switch is placed in position a. What is the time at which the capacitor
reaches 70% of its maximum charge? Show all work CH‐27‐C‐3: Once the capacitor is fully charged, the switch is placed in position b. At t = 0.020 s after the
switch is placed in position b, what is the magnitude of the voltage across the RESISTOR? Show all work CH‐27‐C‐4: a) Given the circuit below, graph the charge and the current (on separate graphs) as functions of time for 0, 1, 2, …to 5. The capacitor is initially uncharged and the switch is closed at t=0. Show all work b) When the capacitor is fully charged (t=∞), what is the energy stored in the capacitor? Show all work
