Reflection from the Solution to an Exercise with Tellegen's Theorem
Liu Zhao-Yang · Journal of Electrical & Electronic Education · 2008
Enlightened by refrence[2],this article proves that it would make mistakes when Tellegen's second theorem is used to do exercises with the unknown network containing controlled source by means of shifting the network to a concrete example,deducing that Tellegen's theorem could not be used carelessly.When setting examinations,teachers should not state resistance network generally for it is not very distinct,but should notify clearly that the internal network is just composed of resistance.
