- AKirchhoff’s Law
- BNewton’s Law
- CCoulomb’s Law
- DStephan’s Law
Explanation:
Kirchhoff’s Law is used to analyze circuits. This law is important because they represent connections of a circuit. Kirchhoff’s Law provide the constraints that let us find the current flowing and voltage across every circuit element.
