Study Notes

Kirchhoff's Laws

Kirchhoff's laws provide principles for the conservation of charge and energy in electrical circuits.

Kirchhoff's Current Law (KCL)

The primary focus of Kirchhoff's current law is the conservation of charge.
Kirchhoff's current law is based on the principle that the algebraic sum of all currents entering a node is equal to the algebraic sum of all currents leaving a node.

Kirchhoff's Voltage Law (KVL)

Kirchhoff's voltage law addresses the aspect of electrical circuits related to the conservation of energy.
Kirchhoff's voltage law is based on the principle that the algebraic sum of all voltages around a closed loop is equal to zero.
