Design a full-wave regulated power supply using a 5:1 center tapped transformer and an 8 (V) 2 W zener diode that will provide a constant 8 (V) to a load varying from 100 to 500 Ω. The input voltage to the transformer is 110 to 120 (V) rms 60 Hz. Ignore the losses in the transformer and diodes. Determine:
a. Izmax and Izmin
b. Ri and Vsmin
c. Size of capacitor needed
d. Percent regulation when Rz = 2 Ω
e. Power rating of Ri
