What are Kirchhoff’s Laws?
Kirchhoff’s Laws are the foundation of circuit analysis:
- KCL (Current Law): The sum of currents entering a node equals the sum leaving it (conservation of charge)
- KVL (Voltage Law): The algebraic sum of all voltages around any closed loop is zero (conservation of energy)
Why Kirchhoff’s Law Calculator is Essential
These laws are used to solve:
- Complex multi-loop circuits
- Bridge networks and unbalanced Wheatstone bridges
- Supermesh and supernode analysis
