This is a Regulated DC Power Supply design problem.  The students must choose the values of the following parameters for the design:

a) V_Out =  6.0 V or 10.0 V or 12.0 V

b) R_L = ?? ?    and    R₁ = ?? ?

c) Wattage ratings of R₁ and R_L to be determined

d) I_L = 20 mA;    I_ZD = 20 mA;  I_R1 = ??  mA

e) Voltage V_{A_DC}  = V_B + 3 V

f) Turns ratio, n = ??

i) Pick an output voltage number from (a)

ii) Choose the appropriate Zener Diode from the data sheet given below.

iii) Determine the ? values and the wattage ratings of R₁  and R_L.

iv) Determine the peak value of the transformer secondary voltage V_S.

v) Determine the transformer turns ratio n.
