a diagram of an electrical system

Electricity is all around us: it powers our devices, lights up our homes, and enables modern technology to function. But to understand how it all works, we first need to master some basic concepts. This module will guide you step by step through these concepts, starting with the fundamentals and moving on to more advanced topics.The concepts we will introduce in this module took a long time to take shape and be accepted by scholars throughout history. It took more than a century, from Coulomb's experiment in 1785, which marked the birth of this theory, to the publication of the theory of special relativity in 1905, to fully understand the laws of electromagnetism. That’s why we’ll place particular emphasis on the conceptual aspect, so that you can begin now to deeply reflect on the meaning of the physical quantities you’ll encounter as you progress in your studies.
