PHYS208 Fundamentals of Physics II

Answer for Ch. 33, 80P

a)  41.4 W

b) -17.1 W

c)  44.0 W

d)  14.4 W

e) energy is flowing away from that circuit element

f) a=b+c+d to within round-off error

Answer for Ch. 33, 81P

[formula]

Answer for Ch. 33, 84P

a) 76.4 mH

b) 17.8 ohm

The resistive approach would waste energy via dissipation, not the case with the inductive approach.

Answer for Ch. 33, 85P

a) 2.59 A

b)

Vab = 38.8 V
Vbc = 159 V
Vcd = 224 V
Vbd = 64.2 V
Vad = 75.0 V

c) Zero average power associated with inductor and capacitor; the resistor dissipates 100 W of power.
