Circuits & Digital Systems Course ⚖️ AC Power Analysis
🔒

Maximum Power Transfer in AC

Inside this lesson
  • State the complex-conjugate match condition for maximum power transfer with an unrestricted load
  • Derive the resistive-only optimum R_load = |Z_th| and explain why it differs from R_load = R_th
  • Compute and compare the maximum power delivered in both cases for a given Thevenin equivalent
  • Recognize that the resistive-only case is always less than or equal to the unconstrained case
