I have built a Wordpress plugin that is based on jQuery and I am using 
`wp_enqueue_script('jquery');`
to make it all work.

Let say the default version of jQuery loaded by Wordpress is 1.7.2, what would happen if the users installs a theme based on a different version of jQuery?

1. **What version of jQuery will run in the page where the plugin is called**: the default version of jQuery (as I'm using wp\_enqueue\_script('jquery')) or the version of jQuery called in theme?
2. **I can't figure out what version of jQuery will be used if a page includes multiple plugins and if each one of theme uses a different of jQuery**? Will everything mix up and end up in conflicts?

Thanks for your help
