alleryStart learning →Maximum power is transferred from source to load when:
AR_L = ∞
BR_L = R_th (load matched to source's Thevenin resistance)
CR_L = 0
DR_L = 2 R_th
Answer & Solution
Correct answer: B. R_L = R_th (load matched to source's Thevenin resistance)
**Maximum Power Transfer Theorem:** for DC, P_max when R_L = R_th.
Maximum power = V_th²/(4R_th).
Efficiency = 50% at max power.
**AC:** load impedance = complex conjugate of source impedance for max real power.
