How can I reset $PATH to its default value in Ubuntu?

I accidentally unset all the directories of $PATH while trying to add a new one in ~/.bashrc. I opened a new terminal window as I was editing and now $PATH is empty. I'm worried if I boot from another drive to find the $PATH I won't be able to boot into this drive again.

Basically, what is the default result of echo $PATH?

Adding :$PATH to the end of the export line fixed the problem e.g. export PATH=<directory to be added>:$PATH

I add this line to the ~/.bash_rc file instead of the ~/.profile file so I can see the effect immediately in a new terminal and for other reasons based on the information here: https://superuser.com/questions/176404/linux-bash-not-loading-profile-in-new-session

For me, the default output of echo $PATH before adding the new directory is:

/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games
