What are Kirchhoff’s Laws? 

In 1845, a German physicist, Gustav Kirchhoff developed a pair of laws that deal with the conservation 

of  current  and  energy  within  electrical  circuits.  These  two  laws  are  commonly  known  as  Kirchhoff’s 

Voltage and Current Law. These laws help in calculating the electrical resistance of a complex network 

or impedance in case of AC and the current flow in different streams of the network. In the next section, 

let us look at what these laws state.

 

 

 



 

 



Kirchhoff’s Current Law goes by several names as Kirchhoff’s First Law and Kirchhoff’s 

Junction Rule. According to the Junction rule, in a circuit, the total of the currents in a junction is 

equal to the sum of currents outside the junction. 

 



Kirchhoff’s Voltage Law goes by several names as Kirchhoff’s Second Law and Kirchhoff’s 

Loop Rule. According to the loop rule, the sum of the voltages around the closed loop is equal to 

null.

 entering the node is considered positive, likewise, the 

currents I

 and I



5

 exiting the nodes is considered negative in values. This can be expressed in the form of 

an equation: 

I1 + I2 + I3 – I4 – I5 = 0

 

 



 


The term Node refers to a junction or a connection of two or more current-carrying routes like cables 

and other components. Kirchhoff’s current law can also be applied to analyze parallel circuits.

        SUMMARY 



According to Kirchhoff’s Current Law,  

The total current entering a junction or a node is equal to the charge leaving the node as no 

charge is lost. 

Put differently, the algebraic sum of every current entering and leaving the node has to be null. This 

property of Kirchhoff law is commonly called 

Conservation of charge

 wherein, I(exit) + I(enter) = 0.
