Network Theorems (ac) 
 
18.1  INTRODUCTION 
The theorems studied earlier: Superposition theorem, Thevenin’s Theorem, 
Norton’s Theorem, and Maximum Power Transfer theorem have a very similar 
(almost identical) replica for ac circuit with the only change from just numbers and 
resistances to phasors and impedances.  
 
18.2  SUPERPOSITION THEOREM 
 
The only variation in applying this theorem to ac networks with independent sources 
is that we will now be working with impedances and phasors instead of just resistors 
and real numbers.
