Uses of Kirchhoff’s Law

History of Gustav Robert Kirchhoff

Gustav Robert Kirchhoff was a German physicist who was born in Prussia a state under German Empire on 12 March 1824. He gave his contribution to the field of electrical circuits, black body radiation, and spectroscopy. He was the one who coined the term ‘Black Body Radiation’. Kirchhoff’s Circuit Law is the combination of Kirchhoff’s Voltage Law (KVL) and Kirchhoff’s Current Law (KCL) which were published in 1845 as part of his doctoral dissertation....

Kirchhoff’s Laws Definition

Kirchhoff’s Laws are the basic laws used in circuit analysis to solve complex circuit problems. Gustav Robert Kirchhoff gave us two laws Kirchhoff’s Voltage Law (KVL) and Kirchhoff’s Current Law (KCL) which are widely used in circuit analysis. Kirchhoff’s Voltage Law (KVL) is based on the conservation of energy, whereas Kirchhoff’s Current Law (KCL) is based on the conservation of charge. These laws help us to calculate the resistance or impedance connected to the circuit and the current flowing through them....
