Electrical engineering you learn with your hands. Turn the battery up until Pip pops, then wire the real circuit and make it pass.

How every unit works
See it. Try it. Build it.
An idea, then an experiment to get a feel for it, then a real circuit that has to pass the checks. Here’s the very first unit, start to finish.
See it:
The idea, in plain words.
Charge only flows round a complete loop. Break the loop anywhere, and everything in it stops.
Short screens with pictures, then a few quick questions, with a hint whenever an answer is off. Try it:
An experiment to play with.
Snip any wire. One gap, anywhere in the loop, and Pip goes dark. Join it again and Pip lights.
Build it:
A real circuit, checked.
Wire it on the simulator’s board, run it, and pass the challenge’s checks. Here, one missing wire closes the loop.
