The Flow of Power
Stop guessing and start building. Learn to see electricity as a flowing current you can direct, control, and use to bring your own gadgets to life.
Like Duolingo, but for The Flow of Power. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
A short one: 12 levels across 2 sections, about 24 minutes end to end, roughly 5 days at five minutes a day. It moves through Making the Connection and Thinking Like a Builder. It starts from scratch.

Key ideas in The Flow of Power
- Electricity must return to its source to flow
- The load is the part that does the actual work
- An open circuit prevents any work from being done
- The load consumes electrical energy to create light, heat, or motion
- The negative terminal is the necessary destination for the loop
- Wires and batteries are the path and source, not the load
- The necessity of a closed path for electrical work
- Identifying the role of the load in a circuit
- Voltage is the potential energy or pressure
- Current is the physical flow of charge
- Electricity takes the path of least resistance
- Without a load to use the energy, the circuit generates dangerous heat
- Short circuits can drain batteries instantly or cause damage
- Recognizing the danger and cause of a short circuit
- Higher voltage can push more current through the same path
- Distinguishing between voltage and current

One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives The Flow of Power the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
Here's what playing it feels like
A real question from this course. Take your best guess.
