I have a physics assignment where I need to find a simple electronic car circuit and make a simple electric circuit that has the same function the electronic circuit has.

Now i'm pretty much stumped on this cause we've only been taught the basics like Ohms law and Kirchhoff's laws and i'll stuck.

Now here's the circuit I chose:

Whoever creates an electric circuit that has the same function as that or helps me turn that into an electric circuit will get 10+ Points.

btw I understand the theory behind it I just don't really understand what you'd replace a transistor with in an electric circuit.

Also by Electric I mean a non-electronic circuit.

Right now, I am a junior in high school. I love physics,and math. The thing is I cant decide whether I should become/major in computer software engineering, computer hardware engineering, or electrical engineering. I really want to be more of an electrical engineer or maybe computer hardware engineer because I love messing around with electronic things and computer such as opening them up and looking around and learning all sorts of stuff about circuits and then putting them back together again. But then,I hear that computer software engineering pays quite well but I dont like coding and staring at computer screen and typing and all. I love “physical stuff.” My parents want me to be a computer software engineer but I am quite vacillating. My first choice is electrical engineering though. I want to know whether electrical engineering would pay a lot. I dont have to stay in silicon valley.I can travel anywhere in the USA or even other developed nations as long as I make good money and like what I am doing and having a good life. So please help me!!

As the title explains I would like to learn basically what a sophomore/junior level EE student would learn. I’m looking for the practical side of circuitry, and less towards the theory. Obviously you need theory to understand practical and vice vursa, but I would like to actually be able to make basic circuits not just understand how they work. I’m a sophomore chemical engineering student and I’ve taken Physics Electricity and magnetics so I understand ac, dc, R,C, L Circuits. Also, is there any book or site that has different chips and what they do etc?

The last thing is I want the book to be cheap…

These are 2 I’ve found through amazon that people seemed to like. Anyone used these?
