I agree, but didn't really want to start differentiating between the two as otherwise some may have thought I was being a pedant. Oh, I see that someone already has!

The reason I said that the two are the same for practical purposes is that most of the internet seems to use the term parasitic drain to describe the total of the two quantities (incorrectly I think you will agree, Mike)

If we do want to be pedantic, or indeed demonstrate a level of pedantry, what I was doing was verifying that my car's post switch-off transient and long-term steady-state quiescent power consumption fell within expected bounds and was not excessively increased by the presence of parasitic power drains (consumptions). Of course some of the quiescent drain will include drain due to parasitic effects within the electronic components but for our purposes they are an inherent part of the quiescent consumption.

Everyone happy?
