Surprised the hell out of me also. I grew up with tubes and all my
instruction was based on 40's and 50's theory. I have know idea when
things changed, but I went to confirm my definitions for an
unpublished book and this . . . is what I found.

huh????

note that Amps are the only unit that is standard. Volts are derived
from Watts. Ohms are derived from Volts and Amps!

No more E=IR.
