19913 Q3/A- Design a voltage regulator circuit by using variable input voltage. Use the following information in your design: Izk = 0.25mA, PD(max) =1W, voltage Zener Vz-10v, the resistance R-22002. rosme B-What is a Zener diode?

4. What does Ohm's law state? what are the differences between an Ohmic resistance and Non-Ohmic resistance? Explain the difference between Forward and Reverse Bias in a Diode. Then, write down Kirchoff's laws. Draw an example of a circuit that has both scries and parallel resistors. Determine the equivalent resistance from there.

7. A diode (V7 = 0.7 V, rr 10 N) and a Zener diode (Vz = 5.6, rz= 25 2) are connect as in the below circuit. Calculate the output voltage if the current in the circuit is 29 mA. 4702 Vout 24V 100N
