Gustav Robert Kirchhoff was a German physicist who contributed to the basic understanding of spectroscopy, electrical circuits, and the emission of black-body radiation by heated objects. Kirchhoff’s circuit laws are two equalities that deal with the current and potential difference in the lumped element model of electrical circuits. There are two laws as follows:
Kirchhoff’s current law (KCL) or Kirchhoff’s first law
Kirchhoff’s voltage law (KVL) or Kirchhoff’s second law
According to Kirchhoff’s Voltage Law,
The voltage around a loop equals to the sum of every voltage drop in the same loop for any closed network and also equals to zero.
In simple terms, Kirchhoff’s Voltage Law (KVL) deals with the conservation of energy around a closed circuit path.
