Extracted text: *42. a. Determine VL, IL, Iz, and IR for the network of Fig. 2.186 if RL = 180 2. b. Repeat part (a) if Rµ = 470 N. c. Determine the value of R, that will establish maximum power conditions for the Zener diode. d. Determine the minimum value of R, to ensure that the Zener diode is in the "on" state.
