The Flow of Power: Basic Circuits
Stop guessing and start building. Learn to direct the invisible force of electricity to power lights, motors, and your own inventions.
Like Duolingo, but for The Flow of Power: Basic Circuits. 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 Building Your First Loop and Measuring and Mastering Power. It starts from scratch.

Key ideas in The Flow of Power: Basic Circuits
- Electricity requires a continuous path to flow
- The power source provides the voltage (push)
- A break anywhere in the loop stops the flow of electrons
- The load is the component that performs the intended task
- Air acts as an insulator that blocks the circuit path
- A circuit without a load is dangerous, and without a source is inert
- The necessity of a closed loop for current flow
- Identifying the essential roles of power and load
- LEDs are polarized and only allow current in one direction
- The longer leg of an LED usually connects toward the positive terminal
- Flipping a polarized component is a standard troubleshooting step
- Electricity takes the path of least resistance
- Bypassing the load causes a massive, rapid flow of energy
- Short circuits generate heat and can melt wires or damage batteries
- Applying polarity rules to component orientation
- Recognizing the danger and cause of a short circuit
