 •Example 4
 •
 •Determine the current I for the circuit shown in the figure below.
  
 
  
  
  
  
   
   
   
   
   
   
   
   
   
   
   
   
  
  
  
   
  
  
 
  
  
 
  
  
  
 
  
   
   
   
  
   
   
  
   
  
  
  
  
 
  
  
  
 
 I + 4-(-3)-2
 = 0
 ŽI = -5A
  
 This indicates that the actual current for I is flowing       in the opposite direction.
 We can consider the whole enclosed area as one “node”.
