# E11 Assignments

Homework is typically due twice per week.

1. The online assignment will use the textbook web page (link) and must be completed on time, usually by 6:00 a.m. on Thursdays.
2. The written assignment will be turned in to Cassy Burnett in the department office to be graded. It will usually be due at noon on Mondays, and will be penalized by 25% if it is turned in late.

Week 1:

• Online assignment: Link. It is due Thursday 6:00 a.m. - but see email I sent if you are having difficulties. Email is also available on "News" section of moodle page
• Written assignment to be done by hand. Due Monday at noon.
2.8, 2.11, 2.19, 2.24
• Solution

Week 2:

• Online assignment: Link. It is due Thursday 6:00 a.m. There is a 10% deduction for each day it is late.
• Written assignment to be done by hand. Due Monday at noon.
2.52, 2.55 (Simplify the circuit as much as possible before starting), 2.62 (Resistance is futile: Use the fact that if you look at the resistance to the right of the leftmost 3 resistors, it is also equal to Req), 2.66 (Review Y-Δ, or π-T, transformations), 2.69
• Solution

Week 3:

• Online assignment: No online assignment this week because of quiz
• Written assignment to be done by hand. Due Monday at noon. You should feel free to make simplifications (e.g., parallel or series combinations) before starting the solution of the circuit if it makes the solution easier.
For each of the assigned problems make sure that, in addition to the specified solution, that you also:
• add a sentence explaining how you could determine the number of equations needed by examining the circuit.
• neatly write the resulting matrix equation, A·v=b
3.1, 3.3, 3.10, 3.11, 3.13, 3.24

Week 4:

• Online assignment: Link. It is due Thursday 6:00 a.m. There is a 10% deduction for each day it is late.
• Written assignment to be done by hand. Due Monday at noon to Cassy Burnett in the department office.
3.29, 3.31, 3.47, 3.50, 3.51
• Solution

Week 5:

• Online assignment: No online assignment this week because of quiz
• Written assignment to be done by hand. Due Monday at noon to Cassy Burnett in the department office.
3.53, 3.73, 4.4, 4.7, 4.39, 4.40, 4.41. For problems 4.4 plot the inductor voltage, and for problem 4.7 plot the capacitor current. You should also know how to solve 4.39, 4.40 and 4.41 with your calculator (assuming it can handle complex numbers).
• Solution

Week 6:

• Online assignment: Link. It is due Thursday 6:00 a.m. There is a 10% deduction for each day it is late.
• Written assignment to be done by hand. Due Tuesday at noon to Cassy Burnett in the department office. Late homework will not be accepted this week so I can post solutions Tuesday afternon, so you can use them to study for the exam on Wednesday morning.
4.56 (also write an expression for I(t) and I1(t); assume ω = 1rad/sec.)
4.64 (use current divider), 4.65, 4.74
Repeat 4.74 using superposition
• Solution

Week 7:

• Online assignment: No online assignment this week.
• 5.1, 5.2, 5.11, 5.12 For 5.11 and 5.12 to find currents and voltages at equilibrium conditions (t=0- and t→∞) remember that for equilibrium conditions, derivatives are zero so the current through capacitors is zero (capacitor acts as open circuit) and voltage across inductors are zero (inductor acts as short circuit).
