Enjoy Circuits, a unique word game with daily challenges!

May 4, 2026 · Electric circuits are classified in several ways. A direct-current circuit carries current that flows only in one direction. An alternating-current circuit carries current that pulsates back and forth …

Explore and experiment with interactive circuit simulations to learn about batteries, resistors, light bulbs, switches, and electrical concepts like Ohm's law.

Bring your 3D designs to life with Circuit Assemblies using Tinkercad.

In this article, we’ll explain circuit in electricity, explore types of electric circuits, their applications, and clarify the difference between electrical circuits and electrical networks.

These free electronic circuits are properly tested and can be found with schematic diagrams, breadboard image or PCB, a detailed explanation of working principle and a demonstration video.

When the applet starts up you will see an animated schematic of a simple LRC circuit. The green color indicates positive voltage. The gray color indicates ground. A red color indicates negative voltage. …

An electronic circuit can usually be categorized as an analog circuit, a digital circuit, or a mixed-signal circuit (a combination of analog circuits and digital circuits).

Cross-window copy/paste lets you easily explore and re-mix parts of public circuits from the CircuitLab community. Mixed-mode circuit simulation lets you simulate analog and digital components side-by …

When it comes to electrical circuits, there’s a lot to remember and understand. We've got you covered with this Intro to Circuits BBC Bitesize guide.
