WebMar 23, 2024 · Small signal "resistance" is something different. r = d V d I Small signal "resistance" tells us the change in voltage for a small change in current. For a non-linear device, V I ≠ d V d I (Except perhaps for some very specific values of V and I). So, we cannot use r to determine either V or I. That is why r is not used in DC analysis. Share Cite
