Maximum Power Transfer Condition

 

Maximum Power Transfer Condition

Definition:
In AC circuits, maximum power transfer occurs when the load impedance matches the complex conjugate of the source impedance.

Example:
If the source impedance $Z_s = R_s + jX_s$, the maximum power transfer occurs when the load impedance $Z_L = R_s - jX_s$. This ensures maximum energy delivery to the load.
