What is Millman's Theorem

Principle of Millman's Theorem:

Statement:       
                     
                       The utility of Millman’s Theorem is that the number of parallel voltage sources can be reduced to one equivalent source. It is applicable only to solve the parallel branch with one resistance connected to one voltage source or current source. It is also used in solving network having an unbalanced bridge circuit.




Properties of Millman's Theorem:


  • The theorem is applicable only for linear network i.e. the networks with R, L, C, transformer and linear controlled sources as elements.
  • The presence of dependent sources makes the network active and hence millman's theorem is used for both active as well as passive networks.
