plugged it into a current bush?
Nope, a flying kite with a key... Current was not quantified until 1881: "ampere (n.) 1881, "the current that one volt can send through a resistance of one ohm," from French ampère, named for French physicist André-Marie Ampère (1775-1836). Adopted by the Electric Congress at Paris in 1881. Shortened form amp is attested from 1886."
Having said that, I realize the official unit for current comes well after it's discovery. And, what a internet rabbit hole this brought me to
: Electricity was "known" for a long time; Egyptian texts from 2750 BC mention it found it in some fish. Franklin few a kite in 1752. Etc. First battery is 1800, by appropriately named Alessandro Volta.

Cool.
Which brings me to a question the internet could not answer for me: how do you trim a current bush?
