Chapter 3  Nodal and Loop Analysis Techniques 

Nodal Analysis: An analysis technique in which one node in an N-nodes network is selected 

as the reference node and Kirchoff’s current law is applied at the remaining N-1 nonreference nodes. !!!! What ideal did you get ? 

Loop Analysis: An analysis technique in which Kirchoff’s voltage law is applied to a 

network containing N independent loops. !! How many equations will you get ?

There fore, the two equation for the two unknown node voltage v1 and v2 are

The determinant is

v2=vx

Zi= Vi / Ii
