Introduction
Kirchhoff's Laws are fundamental principles used to analyze electrical circuits. This tutorial demonstrates how to build and verify KVL and KCL using MATLAB Simulink and Simscape Electrical.
Kirchhoff's Voltage Law (KVL)
The algebraic sum of all voltages around a closed loop is zero.
Equation: ΣV = 0
Kirchhoff's Current Law (KCL)
The total current entering a node equals the total current leaving the node.
Equation: ΣIin = ΣIout
MATLAB Simulink Implementation
- Open MATLAB and Simulink.
- Add Simscape Electrical components.
