Electrical Engineering QUESTION #2136

Question 1

According to Tellegen's Theorem, for any network with $b$ branches and $n$ nodes, the algebraic sum of power delivered to all branches at any instant is:

Always positive
Dependent on the type of elements
Zero✔️
Equal to the total energy stored

Correct Answer Explanation

Tellegen's Theorem is based on KCL and KVL; it states that $\sum_{k=1}^{b} v_k i_k = 0$, meaning the sum of power delivered to all branches in a network is zero.
