That depends on how much current (Amps) is flowing through the copper.
The voltage you lose in the copper will always be (A) times (R).
'A' is the current (amps) in the copper.
'R' is the resistance of the copper. You can look that up in a product catalog,
or measure it with a really good ohm-meter.
