Both these tags are typically used when the poster isn't intending to dig for an actually descriptive tag. Neither of these tags should be existing, as they apply to every single question on this network.
Both tags are indicative of a bad question:
- Average SE.EE question score: 2.56
- Average electricity question score: 1.17
- Average electrical question score: 0.60 (!)
I don't mean to imply the tag makes the question bad, but tagging something with electrical is a pretty clear indication that the question hasn't seen the required amount of TLE, and the site would, in my humble opinion, be better off if we enforced not tagging with this pseudo-tag.
