Question

According to Millman’s Theorem, if there are n voltage sources with n internal resistances respectively, are in parallel, then these sources are replaced by?

(a) single current source I’ in series with R’

(b) single voltage source V’ in series with R’

(c) single current source I’ in parallel to R’

(d) single voltage source V’ in parallel to R’

This question was addressed to me by my college professor while I was bunking the class.

My question is taken from Millman’s Theorem topic in chapter Useful Theorems in Circuit Analysis of Network Theory

Answer 1

Right answer is (b) single voltage source V’ in series with R’

To explain I would say: Millman’s Theorem states that if there are voltage sources V1, V2,…… Vn with internal resistances R1, R2,…..Rn, respectively, are in parallel, then these sources are replaced by single voltage source V’ in series with R’.
