In this chapter, we will discuss the two important laws provided by Kirchhoff and their applica-
tions in solution of network problems with plenty of solved examples.
2.1 KIRCHHOFF’S LAWS
There are two Kirchhoff’s laws. They are Kirchhoff’s current law and Kirchhoff’s volt-
age law. By applying these two important laws, we are able to solve electrical network
problems.
2.1.1 Kirchhoff’s Current Law
This law is applicable to a node or junction in an electrical circuit.
Kirchhoff’s current law (KCL) states that the algebraic sum of all the currents meeting at a
junction or a node in a circuit is equal to zer ...
