Oddly enough, we mean two hots, one common, and one ground. total of four
wires.

Red and black are hot, and white is neutral and bare is ground.

I am going about 150 feet to a shed, and plan to run number 10 gauge wire.
This is simply a shed, and I want to be able to run power tools and have
some lights in the shed. I plan to use UF wire, and of course go 2 feet
underground.

Someone advised to run 10/3 instead of 10/2, but I forgot the reason
why. It seems they were indicating I could have TWO circuits instead of
one. Is that correct ? If so, then it seems that I could have 2 separate
20 amp circuits, but I am not sure.

When we say 10/3 wire, is that two main live wires, and one common
ground ??

Thanks a lot !!
