If there are N nodes in a circuit, then the number of nodal equations that can be formed are?(a) N+1(b) N(c) N-1(d) N-2This question was posed to me in an online interview.This question is from Nodal Analysis topic in section Steady State AC Analysis of Network Theory

Answer»

The CORRECT answer is (c) N-1

To EXPLAIN I WOULD say: If there are N nodes in a circuit, then the number of nodal EQUATIONS that can be formed are N-1. Number of nodal equations = N-1.
