What are circuit simulations

Circuit simulations for education are interactive digital representations that allow students to build, modify, and analyze electrical circuits in a safe and controlled environment. These tools usually incorporate mathematical models that reproduce the real behavior of components, letting users manipulate variables and observe how the results change in real time.

Our collection of online simulations covers the fundamental aspects of electrical circuits, from basic concepts to more advanced configurations with resistors, switches, power sources, or measurements with instruments. Among the different tools available, our simulations are based on the PhET electric circuit laboratories. To make learning easier, the entire subject matter is divided into different thematic units, each of which includes several simulations. In each of these simulations, a circuit template is provided for visitors to build, experiment with, and analyze.

As a complement to the simulations in this collection, users are encouraged to visit the physics simulations in the area of electromagnetism, particularly those related to electrical circuits.

Advantages of using simulations to learn or teach circuits

Using simulations offers several advantages for learning about electrical circuits, including:

Better conceptual understanding.

Simulations help visualize abstract concepts such as current or potential difference, making for deeper and longer-lasting understanding.

Greater interactivity.

They allow you to build and modify circuits safely, change components and values without risk, which increases student motivation and engagement.

More flexibility.

You can try configurations that would be difficult to set up in a real lab, explore different scenarios, and repeat experiments as many times as needed.

Maximum efficiency.

Simulations save time and resources, eliminating the need for physical materials and allowing you to experiment with complex circuits immediately.

Greater accessibility.

They can be used from any device with an internet connection, making distance learning easier and providing access to educational resources even without a lab.

Our simulations work online; you don’t need to download any application or software, just use any regular browser (Chrome, Bing, Opera, etc.) on your computer, phone, or tablet.
