Learn English – How to make sentence with charge

american-english

I want to make sentence with charge.
but I'm not sure as to sentence structure with charge.

For example.
Is something just charge of something?
Can I make like this?
If I wrong please let me know about it.

And I want to know the case of sample without 'of' at above example.

UPDATE:
If I want to ask as to who's responsibillty? How do I do?

Best Answer

If someone is responsible for something (say, a project, or a child), we usually use the expression in charge (of). For example:

David is in charge of the parts department.

"Remember, Tommy, while we are gone the babysitter in charge."

The first sentence means David manages the parts department. The second sentence means Tommy is expected to mind (or obey) the babysitter while his parents are gone.
