Get renamed file new name

Hello all. What I'm wanting to do is rename a file and then do some things with the new file name.

1. I want to view the new file name with the full path

2. I want to output the new file name with the full path to a text file or csv file

Here is what I have for outputting the renamed file into a text file, but it isn't working:

cls
$resultsfile = "C:\results3.txt"
clear-content $resultsfile

foreach($item in gc C:\RENAME.txt){

    Rename-Item  $item "1.txt" | out-file $resultsfile -append
}
notepad $resultsfile
