Chapter 10, Problem 10.1

(choose chapter or problem)

The following sets of values for and i pertain to the circuit seen in Fig. 10.1. For each set of values, calculate P and Q and state whether the circuit inside the box is absorbing or delivering (1) average power and (2) magnetizing vars i = 10 cos(vt + 170) A. v = 80 cos (vt + 120) V,i = 2 cos(vt + 50 ) A. v 150 sin(vt + 25 ) V, i = 5 cos(vt - 75 ) A. v = 18 cos(vt - 30) V, i = 4 sin(vt + 60) A. v = 250
