Question

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-1

I 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 1

The correct choice is (b) n+3

Explanation: Standard formulae: b-(n-1)

                             Given b-(n-1) =4 -> b=4+ (n-1) =n+3.
