Minimum value of rl that can be used, Electrical Engineering

Verify the minimum & maximum load current for which the zener diode will keep regulation. Find the minimum value of RL that can be used.

The zener diode has VZ = 12V, IZK = 1mA IZM = 50mA and the diode has internal zener resistance of 5 ohms
VZ = 15V at IZ = 17mA, IZK = 0.25mA and ZZ = 14 ohms and PD(max) = 1W

a)  Find VOUT at IZK and IZM

b)  Determine the value of R that should be used

c)  Calculate the minimum value of RL that can be used

d)  Find the minimum & maximum value of load current

e)  Locate the line regulation
