Why are leads from the negative terminal considered grounds?

I'm using a 9V battery with a 5v regulator as a power supply. What I can't grasp is why I place the regulator in the (+) lead of the battery. If electricity is electrons flowing, and the excess electrons come from the (-) terminal of the battery,…

How should one terminate litz wire?

When using Litz wire, the accepted method of stripping the wire is by dipping it in a solder bath, which effectively turns the end of it into solid-core wire, so my question is thus: How good is the contact between a tightly-screwed-down screw-type…
