Kirchhoff's Laws are fundamental principles in electrical circuit theory that govern the behavior of electrical circuits, specifically in terms of current and voltage. They are named after Gustav Kirchhoff, a German physicist who formulated them in the mid-19th century. 1. **Kirchhoff's Current Law (KCL)**: - KCL states that the total current flowing into a junction (or node) in a circuit must equal the total current flowing out of that junction. - Mathematically, it can be expres...
