What are the advantages and disadvanteges of thevinins and norton theorem?

Thevenin's and Norton's theorems simplify complex linear circuits into equivalent circuits, making analysis easier. Thevenin's theorem presents a circuit as a single voltage source and resistance, while Norton's presents it as a current source and parallel resistance, allowing flexibility depending on the analysis needed. However, both theorems only apply to linear circuits and can become cumbersome for circuits with non-linear components. Additionally, converting between the two forms may introduce calculation errors if not done carefully.
