Get the value of the minimum load resistance that can be used to keep the zener diode regulating.Zener voltage, VZ = 6.1V and incremental resistance, rz = 0 a) Determine the value of Ri such that the Zener diode remains in breakdown if the load current varies from IL = 20 to 200 mA and if the input voltage varies from VI = 8.6 to 10V. Assume IZ(min) = 0.1IZ(max). b) Determine the power rating required for the Zener diode and the load resistor. c) If the position of Zener diode were changed to be in forward bias region, will the voltage regulator still work properly?
