CloudLabs Mixed Circuit vs UCircuit

In this simulator, Ohm's law must be used to find the value of three resistors in a mixed circuit, whose colored bands have been erased. For the development of this practice, the current and voltage that circulate in the circuit must be measured. The laboratory has a voltage source, a breadboard, a multimeter, resistors and connection cables.

UCircuit — Your First Engineering Lab UCircuit is a playful, visual learning app that turns electricity into something children can touch, move, and understand in seconds. Designed as a first engineering lab, UCircuit helps young learners — including parent-guided early learners — explore how circuits work through safe, interactive play. What UCircuit is: • A guided circuit playground where children build simple and advanced circuits step by step • A safe, no-login, no-account experience focused entirely on learning and creativity • A bridge between play and engineering thinking: cause and effect, logic, sequencing, and problem-solving What kids can do: • Start with a beginner-friendly first lab: Battery + Bulb + Switch • Instantly see how circuits open, close, and flow • Explore interactive labs across multiple themes and difficulty levels • Learn by experimenting — animated feedback clearly shows what works and what needs fixing • Earn badges, save favorites, and build confidence through progress Why UCircuit works for young learners: • Clear visual language and simple, intuitive interactions • Fast feedback loops — children see results immediately • Designed for guided parent–child learning • Encourages curiosity and experimentation without fear of “breaking” anything Pro Unlock: The free experience includes the first core lab. A one-time Pro unlock opens all additional guided labs and the Open Lab Builder for fully custom experiments. No subscriptions. Learn at your own pace. Our mission: UCircuit aims to be the best early engineering companion, making electricity intuitive, fun, and confidence-building from the very first interaction.
