    | Steps to
    determine the node voltages: 
 |  | 
   
    |  | 
   
    |  | 1. | Select a node as the reference node. 
 |  | 
   
    |  | 
   
    |  | 2. | Assign voltages v1,v2,…,vn-1 to the 
 |  | 
   
    |  | remaining n-1 nodes. The voltages are 
 |  | 
   
    |  | referenced with respect to the 
 |  | 
   
    |  | reference node. 
 |  | 
   
    |  | 
   
    |  | 3. | Apply KCL to each of the n-1 non-reference 
 |  | 
   
    |  | nodes. Use Ohm’s law to express the branch 
 | 
   
    |  | currents in terms of node voltages. 
 |  | 
   
    |  | 
   
    |  | 4. | Solve the resulting simultaneous equations 
 |  | 
   
    |  | to obtain the unknown node voltages.
