Circuit Champ
Drag a battery, a resistor and a bulb onto the workbench. Wire them. Press Play and watch the electricity move. A hands-on circuit simulator that teaches electronics by doing.
Free to install · Android 7.0 and up · No account needed to start
- Drag-and-drop workbench with live simulation: wires auto-route, current animates, bulbs glow and LEDs burn if you skip the resistor
- Guided training, one component at a time: multimeter, batteries, resistors, switches, SPDT and LEDs
- Ranked challenges with star times: Wire It, Remake and Fix It
- A real multimeter (volts, amps, ohms) and an on-screen Ohm’s Law calculator
- Sandbox Build mode with real resistor values, parallel and series circuits, and ten local save slots plus cloud saves
- Profile with stars, streaks, complexity progress and achievements

Learn electronics by doing
Every part in Circuit Champ behaves like the real thing. A rocker switch opens and closes the loop. A 2.5 V bulb on a 9 V battery needs the right resistor to glow. An LED without one burns out. Drop in the multimeter to read the volts, and let the Ohm’s Law panel do the maths.
Start with the guided training nodes, climb the ranked levels, then build anything you like in the Sandbox and save it to My Circuits.
