A group of fellow students and I are designing a game for a project, meant as an introduction to the subject of general electrical engineering.

It is going to be at a very basic level, introducing primarily voltage, current, resistance, in combination with Ohms Law.

We would also like to introduce Korchoffs. 1 Law (maybe 2. Law also)

Does anybody have some good suggestions for simple curcuit designs, that could introduce these concepts. It would be good to be able to introduce them one-by-one, although we know that introducing voltage, current and resistance can be somewhat difficult without directly using Ohms Law directly from the start. We are open to suggestions though!

If anybody has any ideas for some basic curcuits, please let me know! It is very much appreciated!
