  3.) Consider initial conditions for iL and v at t = 0+
  4.) Write KCL at top right node, valid for t > 0.
       Use variables iL(t) and v(t).
  5.) Use the integral from of v = L(diL/dt) to
       eliminate iL(t) from the KCL equation.
  6.) Differentiate both sides of the KCL equation
       and solve the resulting D.E. for v(t).

Note 1) Homework must be ready for peer grading and discussion in class on the first listed due date. It must be turned in for a final grade on the second listed due date. Peer grading will be 1/5 (20%) of the homework grade.

Note 2) If a "#" follows the "returned" date, then the solution key is posted on the cork board across the hall from room S233.

Note 3) Problems sets shown above with no "assigned" date are tentative. More problems might be added, expected due dates might change, but problems shown will eventually be assigned.
