Pretty simple,  It's all explained here:

and don't forget Bernoulli's principle.

Thanks all. Lots to learn? I was basically wondering if, assuming no wind, I'm drifting with a 3MPH current, and I drop a 3 way rig with a spinner in 100' of water, will it be spinning, or hanging vertical (ish).

Pretty much hanging vertical.

Definitely spinning.Thats why we backtroll to stay vertical while jigging or mooching in current.

So do you backtroll against the current to slow down your drift?

I might rethink my answer, 3 mph is quite a bit of current.  I usually only back troll on rivers or when you have wind.  It also depends on how deep you are fishing.  If you are jigging salmon 50' down in 700' of water I would say you are pretty much fishing under the boat and no spin on a spinner.  If you are fishing halibut on the bottom, you will need to back troll as the current on the bottom is very minimal compared with the top where your boat is.

You can usually tell by line angle either in the rod or downrigger if you are using one.  If it's straight down or nearly so, there isn't much water movement over the lure.

Easy answer, buy one of these, only $750 to answer the question:
