Fórmula
## Maximum Power Transfer Theorem Max power is delivered when R_load = R_th. ### Formulas **R_load = R_th** **P_max = V_th^2 / (4 x R_th)** Efficiency is 50% at this point.
Ejemplo Resuelto
V_th = 10 V, R_th = 50 ohms.
- 01R_load = R_th = 50 ohms
- 02P_max = 100 / 200 = 0.5 W
- 03Efficiency = 50%
Preguntas Frecuentes
Why only 50% efficient?
Equal power is dissipated in source and load when they are matched.
Is max power transfer always desired?
No. Power systems prioritize efficiency. Max power transfer matters in RF and signal work.
AC circuits?
Load impedance should be the complex conjugate of source impedance.
