Kirchhoff’s First Law (or current law) KCL
It is based on the principle of conservation of charge. It states that:
- The sum of current that enters the junction equals the sum of current that leaves the junction.
Kirchhoff’s Second Law (or voltage law) KVL
It is based on the principle of conservation of charge. It states that:
- Around any closed path, the sum of all voltage drops on all branches within the loop is equal to the sum of the emf’s of the batteries within the loop.
Note: Kirchhoff’s Voltage Law (KVL) also called Kirchhoff Loop Law.
