Question

Which of the following theorem is applicable for both linear and non-linear circuits?
1. Superposition theorem
2. Thevenin’s theorem
3. Norton’s theorem
4. None of these

Answer 1

Correct Answer - Option 4 : None of these

Concept:

• The theorems like Thevenin, Norton, and Superposition theorems are applicable to only linear circuits but not Non-linear circuits.
• Also, all the above theorems are applicable for both active and passive circuits.
• Whereas KCL and KVL are independent of the type of elements hence they apply both for linear as well as non-linear circuits.

Various Theorem and the circuits where they are applicable is shown below in the table:

Theorem	Applicability
Superposition Theorem	Linear
Thevenin Theorem	Linear
Norton Theorem	Linear
Maximum Power Transfer	Linear
Tellegen	All
Substitution	Linear and Non-Linear
