Network Theorem Short Question Answers Part3

Network Theorem 

What is the basic of nodal analysis?

 
Mesh analysis is based on Kirchoff’s voltage law. On the other hand nodal analysis is based on Kirchoff’s Current  law.

What is the advantage of converting current source into voltage source and vice-versa?

The reason one type of source is converted to another type often simplifies the analysis of a circuit containing both types. Any resistances that are in series with a voltage source, whether it is internal or external resistance can be included in its conversion to an equivalent current source. Same as any resistance in parallel with a current source can be included when it is converted to an equivalent voltage source.
