Problem 1: The switch in the circuit has been closed for a long
time prior to being thrown open at t=0.
Problem 2: For the circuit below, 𝑖𝑠 (𝑡) = 5 cos 10𝑡 𝐴.
Problem #1: The switch in the circuit has been closed for a long time prior to being thrown open at t=0. (a) Determine the Time Constant, T. (b) Obtain the expression for v(t) which is valid for t > 0. (c) Using simulation (Multisim / other circuit simulation app), show the graph for v(t) and i(t). 100 Ω M i 200 Ω 2nF 4 V + t=0 150 Ω www

Problem #2: For the circuit below, is (t) = 5 cos 10t A. a) Use Phasor Analysis and obtain the steady-state expression for the inductor current in its phasor form, IL, and time-domain form, i, (t). b) Determine the complex power delivered by the source, in rectangular form (identify the average power and reactive power) and polar form. Is the PF lagging or leading? is (↑ 202 0.4 H Part 2: Feel free to share your thoughts! 1. What are the challenges/problems you encountered (in this course and this semester in general, with this "new normal" and what have you done to overcome such challenges? 2. Cite some advantages and disadvantages of having online classes vs face-to-face classes. 3. Do you think EEE120 should be delivered for the entire sem and not by batch? Why or why not? Suggest anything that you think might help for the next batch of EEE 120 class. ww
