Extracted text: Q12/ a- Determine V,, 1, Iz, and IR for the network shown in the figure below if RL = 180 N. 470 0. b- Repeat part (a) if RL 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. Rs 220 2 Vz = 10 V RL. VL 20 V PZ max = 400 mW
