Electrical Engineering from Zero
Build a working intuition for electrical circuits from your first closed loop to industrial power and automation. Learn how voltage, current, components, and three-phase systems interact to power modern hardware.
Like Duolingo, but for Electrical Engineering from Zero. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
26 levels across 4 sections, about 52 minutes end to end, roughly 10 days at five minutes a day. It moves through Building Working Circuits, Analyzing and Directing Current, Harnessing AC and Grid Power, and Automating Electrical Systems. It starts from scratch.

Key ideas in Electrical Engineering from Zero
- Voltage is the electrical push or pressure between two points, which can exist even when nothing is flowing
- Current is the actual movement of physical charge carriers through a closed circuit
- Without an electrical push (voltage), charge carriers will not drift in a continuous current
- Current requires a continuous, unbroken conductive loop from one terminal to the other
- An air gap anywhere in a simple series loop stops the flow of charge carriers across the entire path simultaneously
- Electricity does not pile up inside a disconnected component like water in an open hose
- Every conductor offers some resistance that naturally opposes the flow of electric charge
- Thicker conductive paths provide less resistance to moving electrons than thin paths of the same material and length
- Under a fixed voltage push, lowering resistance lets more current flow through the path
- A load is a circuit component that draws current to convert electrical energy into heat, light, sound, or physical motion
- Plain connecting wires are meant to conduct electricity with minimal loss, not act as working loads
- An open switch stops current entirely rather than converting energy
- A short circuit happens when an unintended conductive path bypasses the intended working load
- Because wire or metal clips have almost zero resistance, the voltage push drives an abnormally large current spike
- Large currents generate rapid, intense heat in conductors and batteries, creating fire hazards or component damage
- Ohm's Law states that Voltage = Current × Resistance (V = I × R)
