EE-1223 Basic Electronic Engineering

Assignment No 1

Due Date: 16-03-

Q-1 Find I and V in the figure using ideal diode model

Q-2 Input vi is a 1KHz 10V peak Sine wave. Sketch the output of the circuits and also mention the positive and negative peak values

Q-3 A zener regulator utilizes a zener diode with an internal zener resistance of 5 ohm and the value of resistance in the regulator circuit is 82 ohm. If the supply voltage changes by 1 Volt what will be the change in output voltage

Q-4 A 9.1V zener diode has a nominal voltage drop at a test current of 28mA. The internal resistance of the zener diode is 5 ohms. Find the voltage drop across the zener diode at zener current of 10mA and 100mA

Q-5 Determine the minimum and maximum load current for which the zener diode will maintain regulation. Find the minimum value of RL that can be used.

The zener diode has VZ = 12V, IZK = 1mA IZM = 50mA and the diode has internal zener resistance of 5 ohms
