Question

Is Thevenin's theorem applicable for AC?

Answer 1

Yes, **Thevenin's theorem** is applicable to **AC circuits** as well, with some modifications. In AC circuits, Thevenin's theorem allows you to replace a linear AC network with a single equivalent **voltage source** and an equivalent **impedance** (instead of just resistance as in DC circuits).

Key points for applying Thevenin's theorem to AC circuits:
- The **equivalent voltage** is the Thevenin voltage (\(V_{th}\)), which is the open-circuit voltage across the terminals.
- The **equivalent impedance** is the Thevenin impedance (\(Z_{th}\)), which includes both resistance and reactance (inductive and capacitive elements).

In summary, the theorem works the same in AC circuits, but instead of dealing only with resistance, we deal with complex impedances.

Answer 2

Yes, Thevenin's Theorem is applicable for AC circuits as well. The process is similar to that used for DC circuits, but with AC, you need to consider impedance rather than resistance, and account for phase differences. Are you working on a specific AC circuit problem?
