**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.
