A) Find VL, IL, IZ and IR for the circuit shown below if RL is 2000. B) Repeat for RL 7000. C) What value of RL will dissipate the maximum rated current for the Zener diode? D) Find the value of RL minimum that will ensure that the Zener diode is conducting and providing regulation. Please show your work. 20 V Rs w 220 Ω Vz = 10 V PZmax = 400 mW RL w VL Part A) VL IL IZ IR LNR Part B) VL IL IZ IR Part C) RL Part D) VL
