electricty takes any path to ground not just the easiest. If you are talking in your house type incidents, electricity isn't seeking ground its seeking a path back to the transformer.

What is the better analogy for electricity: like heat (trying to equalize a temperature gradient) or like water (flowing with gravity unless opposed by a pressure that is of a greater force)?

Water is the analogy most teachers would use.

OK, then what is the "gravity" that electricity flows with? What is the field (analogous to a gravitational gradient like elevation) where it moves from a higher to a lower value, all other forces being equal? High to low voltage? Negative charges wanting to do the nasty with positive charges?

I can already feel the concepts dematerializing as I try to pin them down. :(

This is explains better than I could.

Pressure differential.

“He came slightly unstuck in time, saw the late movie backwards, then forwards again. It was a movie about American bombers in the Second World War and the gallant men who flew them. Seen backwards by Billy, the story went like this:

American planes, full of holes and wounded men and corpses took off backwards from an airfield in England. Over France, a few German fighter planes flew at them backwards, sucked bullets and shell fragments from some of the planes and crewmen. They did the same for wrecked American bombers on the ground, and those planes flew up backwards to join the formation.

The formation flew backwards over a German city that was in flames. The bombers opened their bomb bay doors, exerted a miraculous magnetism which shrunk the fires, gathered them into cylindrical steel containers, and lifted the containers into the bellies of the planes. The containers were stored neatly in racks. The Germans below had miraculous devices of their own, which were long steel tubes. They used them to suck more fragments from the crewmen and planes. But there were still a few wounded Americans, though, and some of the bombers were in bad repair. Over France, though, German fighters came up again, made everything and everybody as good as new.”

No post about the white supremacist with Nazi paraphernalia who shot up Houston? I wonder why.
