Some appliance cords and extension cords are marked with ridges or printed lines on one conductor. Do the markings indicate the "hot" or the neutral?

That would be the Identified conductor.

Identified conductor is also a term for the Grounded conductor, which as everyone knows, is the Grounded Neutral conductor on 1 phase circuits.

This Identified conductor does mot always have to be the grounded conductor, as in where a 1 phase 2 wire 240 volt cord was used and it has an Identified conductor on the cord.

That is a good question! I've always wondered how common this knowledge is. I always use this method to figure out which is the neutral on a hanging Fixture.
