Instructions for submitting the mini-project
1. The mini-project should be typed.
2. PSpice results should be shown on the Figures.
3. The mini-project should contain at least: a. Objectives, b. Results


Problem 1
(a) For the circuit shown in Fig. 1, using PSpice obtain the waveforms of the current through and voltage across the inductor, during the charging phase. Put the initial condition for the inductor as 4mA. Also draw the waveform for the power supplied-to /delivered-by the inductor.

Problem 2
For the circuit shown in Fig. 2:
a. It is desired to fix the power consumed in the circuit to 240 mW. Determine the values of the resistors R1 and R2.
b. Verify using PSpice by its parameter /DC sweep feature.

Problem 3

Your neighbor wants to have a device (warning blinker) to be used with a 200V (minimum) neon lamp to flash after each 2 seconds. He contacts you for the purpose. As a matter of your knowledge, courtesy and prestige what circuit you will propose?

[Hint: RC circuit and no PSpice solution. Assume Neon lamp resistance to be very low when it is ON and very high when it is OFF]
