Topic: Network Theory
Which of the following theorem is applicable for both linear and non-linear circuits?
- A. Superposition theorem
- B. Thevenin's theorem
- C. Norton's theorem
- D. None of these
Answer: D. None of these
Explanation: Superposition, Thevenin's, and Norton's theorems are strictly applicable only to linear networks. Tellegen's theorem is valid for any linear or non-linear circuit because it is based on the principles of energy conservation (KCL and KVL), but it is not listed among the options. Hence, "None of these" is the correct answer.
