Question

For Tellegan’s Theorem to satisfy, the algebraic sum of the power delivered by the source is _____ than power absorbed by all elements.

(a) greater

(b) less

(c) equal

(d) greater than or equal

The question was asked in examination.

Question is from Tellegen’s theorem in section Useful Theorems in Circuit Analysis of Network Theory

Answer 1

Correct answer is (c) equal

For explanation I would say: For Tellegan’s Theorem to satisfy, algebraic sum of the power delivered by the source equal to power absorbed by all elements. All branch currents and voltages in that network must satisfy Kirchhoff’s laws.
