Physics is easier to understand when you see it in action. In VoltLab, you explore electricity through interactive experiments, while lessons with AI narration help you understand what’s happening — step by step, at your own pace. What’s inside: • AI-narrated lessons — explore electricity with clear explanations and visual examples. • Interactive experiments — put the laws of physics to the test in experiments you control. • Quizzes with worked solutions — solve problems and reinforce your knowledge with detailed explanations. • No ads — immerse yourself in lessons and experiments without ad breaks. • Offline access — keep learning even without an internet connection. • Free content — learn something new and reinforce what you’ve learnt at no cost. Who it’s for: • School students and school leavers — understand what’s behind the formulas and laws in your textbook. • University students and independent learners — connect theory with what you see in the experiments and better understand electrical phenomena. • Teachers and tutors — show in action what’s difficult to explain in words.

About

Experimenters Circuits

Read full description

A circuit simulator for learning electricity and electronics. Pick components and instruments, place them in the workspace and connect their terminals with cables. The simulation runs while you build, so the meters and lamps respond to every new connection and every turn of a knob. WHO IT IS FOR Students studying electricity in school or at university, teachers demonstrating a circuit to a class, and anyone who wants to understand how a circuit works before building a real one. WHAT YOU CAN DO • Open a ready-made lab — Ohm's law, series and parallel circuits, capacitor charging, resonance, a rectifier, a transistor switch — and change it as you like. • Build circuits from power sources, resistors, capacitors, inductors, transformers, diodes, transistors, lamps, LEDs, switches and fuses. • Measure with an ammeter, voltmeter, wattmeter and oscilloscope. • Operate each instrument with its own controls: turn knobs, flip switches and press buttons. • Slow time down and watch what normally takes a fraction of a second. • Turn off the room light and see the lamps and LEDs glow. • Undo and redo your steps, copy part of a circuit and align everything to a grid. WHEN SOMETHING GOES WRONG The lab does not stop you from making a mistake. Short a power supply, and it switches itself off. Give a lamp too much voltage, and its filament flashes and burns out. An overloaded fuse blows. A source has internal resistance, a cable has a resistance of its own, and a meter slightly changes the circuit it measures. GOOD TO KNOW • Save your circuits and open them again later. • No account is needed to build, measure and save. • Remember: working with electricity in real life requires care.
