  2. Next Maximum Power Transfer Theorem for AC Circuits

  3. Next

  4. Next The power delivered to the load is Phasor current and voltage are where

  5. Next

  6. Next A little forethought saves us some work. (XTh + XL) absorbs no power; any nonzero value only reduces PL. Hence we can put XL = - XTh, so as to get

  7. Next This expression, we have already maximized for purely resistive case, by selecting RL = RTh. Hence, we must have

  8. Next Exercise Show that if the load is purely resistive in an ac circuit, the condition for maximum power transfer is
