## What is Circuit Explorer?

Step into a structured journey through the fundamentals of electricity and electronics with a learning experience designed for iPhone and iPad. Progress through lessons, test your understanding, experiment in an interactive laboratory, and build practical intuition about how electrical circuits behave in real situations.
Begin with a guided path that follows a simple idea: learn, build, prove. Explore thirteen lessons covering essential topics such as current, voltage, resistance, components, capacitors, safety, and the electrical systems hidden in everyday objects. Each lesson combines clear explanations with animated illustrations, key takeaways, related formulas, and in selected cases a connected quiz or laboratory setup.
Keep moving forward with a progress medallion that tracks completed lessons, collected XP, badges, and your daily streak. The Up Next section always points toward the next milestone in your learning route.
Review important equations using Formula Cards. Flip each card to move from formula to meaning, units, explanations, and practical numerical examples. Study Ohm's law, power calculations, series and parallel resistance, charge and current relationships, and capacitor energy concepts in a compact format built for quick revision.
Enter the interactive laboratory and assemble circuits using batteries, resistors, lamps, switches, and wires. Place components on the board with taps or drag and drop interactions, adjust values, and activate the simulation with Power On. Watch lamps illuminate, sparks travel through wires, and live measurements reveal voltage, current, resistance, power consumption, and voltage drops across components.
Take on challenges that reward successful solutions with XP. Light a lamp, control current, install a working switch, reach a resistance target, or achieve a specific voltage drop while learning how each decision affects the circuit.
Strengthen knowledge with five themed quizzes covering electricity basics, Ohm's law, circuit assembly, components, and safety. Instant feedback and explanations help transform mistakes into understanding while preserving your best scores.
Everything works completely offline. Lessons, quizzes, formulas, progress, settings, notifications, and profile photos remain only on your device, without accounts, servers, advertising, or data collection.
