Relationship between branch and loop currents

Tellegen's theorem 1: Consider a lumped network n consisting of N+1 nodes and B branches, let=[ b2DbB,i=. Where

In this chapter we will introduce an important frequency is that network function or parameter reaches a maximum value. In certain simple a networks, this occurs when an impedance or admittance is purely real-a condition known as resonance
