Électricité

Introduction to the principles of electrostatics: positive and negative charges.

Presentation of some laws of electrostatics: charges of the same type repel each other, charges of different types attract each other, and a charged object attracts a neutral object.

Review of two concepts: the charging of neutral objects through direct contact and the neutralization of a charged object through grounding.

Analysis of the structure of a dry cell battery demonstrates how it can be a source of dynamic electricity.

This video introduces other concepts necessary for the complete description of an electrical circuit, such as potential difference.

Studying a simple electrical circuit helps us understand the concept of resistance, a phenomenon that can be explained by the variable number of free electrons and their movement through atoms.
