D 4.61 A designer requires a shunt regulator of approximately 20 V. Two kinds of zener diodes are available: 6.8-V devices with rz of 10 Ω and 5.1-V devices with rz of 25 Ω. For the two major choices possible, find the load regulation. In this calculation neglect the effect of the regulator resistance R.
