These are graded according to accuracy and procedure in an attempt to determine the proficiency gained regarding the presented material. Example 1: Given a diagram of a complex DC resistive circuit network, determine all voltages and currents associated with each device in that network. Example 2: Given the switching, series Resistor-Capacitor-Inductor (R-L-C) circuit connected to a DC source; calculate the response (voltage and current) of the resistor at time, t=20ms after the switch has closed. Example 3: Given the transformer circuit below, calculate the maximum power transferred to the load. Other Example: Other: Homework sets and quizzes are assigned, collected, and graded to determine the students' ability to perform a solution and communicate the correct result to a reader. Example 1: Complete the problem set from the textbook that is assigned according to the schedule (Instructor to select problems from the text as homework). Example 2: Solve the problem on the board working within groups as assigned by the instructor (engineering problem from the textbook displayed). Graded as group work and/or quiz. Repeatable No Methods of Instruction Lecture/Discussion Distance Learning Lecture: Example problems on time variant circuits are demonstrated by the instructor at appropriate times throughout the presentation. Students are then asked to participate and given time to work through additional, similar problems. Students are encouraged to take detailed notes and ask questions to clarify any misunderstanding during the lecture. Distance Learning A lecture is delivered using live/recorded video to present the concepts used to analyze resistive DC circuits. A detailed online discussion will follow outlining the concept, how this concept works and is applied, and a procedure for solving problem sets utilizing this concept. Typical Out of Class Assignments Reading Assignments 1. Read the textbook chapter on reduction of resistive networks by method of "source transforms." Be prepared to interact during a classroom discussion on the procedures of this method. 2. Read the handout on analyzing resistors by color code. Be prepared to answer questions on an exam.
