Question

State and explain superposition theorem. Mention its limitations

Answer 1

Answer:

Superposition Theorem:

Superposition theorem states that in any linear, active, bilateral network having more than one source, the response across any element is the sum of the responses obtained from each source considered separately and all other sources are replaced by their internal resistance.The superposition theorem is used to solve the network where two or more sources are present and connected.

Limitations:

1. This theorem is only applicable to linear circuits.  It cannot be used to measure power.

2. The theorem is only applicable  for the circuits having more than one source.

3.This theorem is not applicable to unbalanced bridge circuits.
