Conservation of charges is a statement that the total amount of charges in a [[Closed system|closed system]] never changes. This definition is true due to experiments. Mathematically, it is saying that our total charges before and after must be the same. $ \begin{align*} \text{Charge before} &= \text{charge after}\\ Q_{i} &= Q_{f} \end{align*} $ > [!warning] We can still create positive charges, just that creating positive charges forces a negative charge to be created as well # Resources <iframe width="560" height="315" src="https://www.youtube.com/embed/JLk_y0en8Jw?si=u30qB-77P0U209NM" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" referrerpolicy="strict-origin-when-cross-origin" allowfullscreen></iframe> --- > 🧠 Enjoy this walkthrough?
