Advantages of Thevenin’s Theorem

Network Theorem Short Question Answers

Advantages of Thevenin’s Theorem

• It reduces a complex circuit to a simple circuit viz a single source of e.m.f. Eth in series with a single resistance RTh. 
• It greatly simplifies the portion of the circuit of the lesser importance and enables us to view the action of the output part directly.
• The theorem is particularly useful to find current in a particular branch of a network as the resistance of that branch is varied while all other resistances and e.m.f source remain constant.
