Kirchhoff's circuit law deals with the current and potential difference (or voltage) in the lumped element model of electrical circuits. 
SOME RELATED POINTS :-
- It was first described by German physicist Gustav Kirchhoff in 1845. 
 - This generalized the work of Georg Ohm and preceded the work of James Clerk Maxwell. 
 - It is widely used in electrical engineering, they are also called Kirchhoff's rules or simply Kirchhoff's laws. 
 - These laws can be applied in time and frequency domains and form the basis for network analysis.
