The obvious question is this; Why would you want to? What you've written is not 'wrong,' but it is completely unnecessary and something that no native speaker would ever say. You already have the answer as to what you should say - 'I need to plug the TV in,' you don't need to add the words 'to make it work,' as everyone understands that a TV needs electricity to work.

No. Using lots of words where a few would be far better does not make a person sound intelligent. If you are doing a test, such as IELTS, then it is true that candidates score more highly if they use sophisticated vocabulary BUT any such vocabulary must be appropriate to the situation that you are describing... the only way this could possibly be appropriate would be for somebody that had completely forgotten the expression 'to plug in,' and so had to use a really long-winded way of explaining their point.
