Origin of the terms "live" and "hot"

Guest
I'm curious as to how the term "live" came to refer to an energized
circuit. It is somewhat of a contradiction, as touching a live wire has
the potential of making someone dead! I can however, see how the term
expresses the idea that the circuit has a certain quality of "life" to
it. I've tried checking etymological sources but the most mentioned is
that the term came about around 1890, which would make sense.

Thanks! :)
