Ohms Law Explained - The Basics Circuit Theory

The video tutorial explains Ohm's Law, a fundamental principle in electronics that describes the relationship between voltage, current, and resistance. It introduces Ohm's Triangle as a mnemonic to remember the formulas: V=IR, I=V/R, and R=V/I. The tutorial provides historical context, explaining why current is represented by 'I' and discusses the concept of electromotive force (EMF). Through practical examples, it demonstrates how to calculate voltage, current, and resistance in circuits, highlighting the direct proportionality between voltage and current, and the inverse proportionality between current and resistance. The video concludes with a discussion on the role of resistors in protecting circuit components.
