The mathematical equation states that our voltage is equal to current multiplied by resistance. $ V=IR $ # Resources <iframe width="560" height="315" src="https://www.youtube.com/embed/78-ZQCCMVGE?si=FHDlpzyHD7Drxv7p" 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> --- > 📂 Want to see more structured notes like these? > Help grow the project by [starring Math & Matter on GitHub](https://github.com/rajeevphysics/Obsidian-MathMatter). ---
