solve the question and demonstrate alor please I want to understand prefectly.

Thank you.

b) A regulator curcuit needs to be designed with an input power supply which has a nominal value of Vps = 20 V and can vary by ± %25 and nominal output voltage of 10 volts. For this purpose a zener diode is employed with specifications given; power rating of 1 W, 10 Name: 1 Number: V drop at Iz = 25 mA, output load current is to vary between I₁ = 0-20 mA and zener resistance of rz = 50 i) If the minimum Zener current is to be Iz = 5 mA, determine the required Rs ii) Determine the maximum variation in output voltage iii)Determine the regulation percent
