Image text transcribed for accessibility: A student designs a zener shunt regulator to produce a regulated output of 10 V using a zener diode specified to have a 10V drop at a test current of 25mA. Incremental resistance of the zener is 10 ohm and minimum diode current = 2mA. Given that supply voltage is 20V pluaminus 25%, and load current can vary between 0mA and 20mA, find Vzo for the zener diode Required series resistance R for zener diode Line regulation Change in Vout corresponding to plusminus 25% change in unregulated supply Load regulation Change in Vout corresponding to 0 - 20mA change in load current Zener diode power rating to handle the worst case power dissipation
