I plead guilty. I knew when I wrote it that the choice was poor but
couldn`t think of a better phrase at the moment.

Terman says on page 76 of his 1955 edition:
"Alternatively, a load impedance may be matched to a source of power in
such a way as to make the power delivered to the load a maximum. (see
footnote) The power delivered to the load under these conditions is
termed the "available power" of the power source."

Walter Maxwell straightened me out on my carelessness on this long ago,
and I repeated anyway. Dang me!
