Asked my father (who used to work for the standards lab at the
Electricity Trust of South Australia) and ..

He had no hesitation is saying it was Intensity.

He said the P was originally for Pressure and the I for Intensity.

He also said that some early PMG instruments, we would call them watt 
meters or Volt Amp meters, used to have two meters, one labelled
Pressure and the other Intensity.



Thats one for the trivia nights!
