Network Theorems in AC

Inside this lesson

Apply Thevenin's theorem to AC circuits by computing the open-circuit phasor voltage V_th and the equivalent complex impedance Z_th
Apply Norton's theorem to AC circuits using I_N = V_th / Z_th
Use superposition with phasor sources at the same frequency, and correctly handle sources at different frequencies by analyzing each frequency separately
State the maximum power transfer condition for AC circuits (Z_load = Z_th*)
