why high current ac plugs harder to remove?
 

Is it just my imagination or is it a little harder to pull an AC
plug that has been carrying high-current (10 A or above)out of
its socket than a low current (1 A or so) plug? If so, anyone
know why?

TIA

All things being the same (receptacle/same type plug)..."your imagination"!

Do you mean the plug was easier to remove before the current went
through it?

Or do you just mean the big plugs capable of high current are harder
to remove?

Sort of related: I've found that no one sells the female end of
extension cords that have 3 outlets and go on simple lamp wire. Now
everything is heavy-duty, and the only one meant for lampcord has only
one outlet. Are light-weight extension cords a violation of code or
FTC rules or something?

The higher current may have heated the contacts a bit and expanded them?

The heavier duty plugs have a u-shaped ground prong that is harder to pull out than plugs with round ground prongs.

Heavier-duty outlets tend to be manufactured with thicker copper that is "stiffer" than the thinner copper used in Walmart type outlets.

If you run too much power thru an outlet and cord, you can actually WELD
the cord's prongs to the outlet contacts. Then you may never remove it.
I've seen this happen several times. The only solution is to replace
both the outlet and the cord (or the plug on the cord).

Generally brass, actually

YES. I have never seen copper contacts!
They are always brass.
