**A little forethought saves us some work**

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 Next

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

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