23. Find the element or elements that must be in the closed con- tainer in Fig. 16.83 to satisfy the following conditions. (Find the simplest parallel circuit that will satisfy the indi- cated conditions.) a. Average power to the circuit = 3000 W. b. Circuit has a lagging power factor. E = 100 V 20° + I = 40 A 20 • 20 Ω ? = FIG. 16.83 Problem 23.
