PHYS208 Fundamentals of Physics II

Answer for Ch. 31, 69P

a) i1 = i2 = 3.33 A.

b) Effective resistance of three resistors is 22 ohm. Thus i1 = 4.55 A; i1 = 2.73 A.

c) i2 = 1.82 A, immediately on the switch opening, since it is now in series with the inductive branch, which had the current 4.55 A-2.73 A through it from part b).

d) All currents diminish to zero after power source is removed.
