Question – Identifying the Wires

Why do I have two black wires on the fixture?


I removed 2 fluorescent light fixtures that were mounted on the ceiling. The 2 fixtures were controlled by a switch. I decided to use the wiring from 1 light to power a ceiling mounted TV.
I have a grounded receptacle. The wire that supplied power to the light has 1 ground, 1 white and 2 black wires.
I would like to verify that the 2nd black wire should be attached to the 2nd brass terminal of the receptacle. Is that correct?

I’m not sure why you have 2 black wires, unless the second black fed the second fixture. If that was the case I would think there would be a second white wire as well. Not knowing the layout and proximity of the fixtures it is not exactly clear what you have going on there.
Can you supply a little more detail, a picture of the layout and wiring would really help.
