If 4 equations are required to describe a circuit by Mesh-Current method and there are n nodes. How many branches are there in the network?(a) n+5(b) n+3(c) n(d) n-1I have been asked this question in class test.The query is from The Mesh-Current Method and Dependent Sources and Some Special Cases in division Techniques of Circuit Analysis of Electric Circuits

Answer»

The CORRECT choice is (B) n+3
