Question

According to Millman’s Theorem, if there are n current sources with n internal conductances respectively, are in series, then the value of equivalent conductance is?

(a) G’=R1+R2+⋯Rn

(b) G’=1/(1/R1+1/R2+⋯1/Rn)

(c) G’=1/((R1+R2+⋯Rn))

(d) G’=1/R1+1/R2+⋯1/Rn

The question was asked by my college professor while I was bunking the class.

This interesting question is from Millman’s Theorem in division Useful Theorems in Circuit Analysis of Network Theory

Answer 1

Right answer is (c) G’=1/((R1+R2+⋯Rn))

The explanation: Let the equivalent conductance is G’. The value of equivalent conductance is G’=1/((R1+R2+⋯Rn)).
