hi, i'm a bit of a noob when it comes to electricity and i have a question involving this negative ion generator i recently got. It runs off ac so i was going to just plug it into an outlet. I was wondering which wire to plug into which hole. There is black and white wire is im pretty sure is black is negative and white is positive. theres this funny plastic cap on the black wire though. any idea on what it is? Thanks!
