We use the definite article before defining a relative clause when we mean specific instances— this is a well-known rule. What if we omit an article in order to say something in a more general way, but assuming specific instances, when the context makes it clear.
Example:
Computers that are now in this room, are powerful.
Is this grammatically correct? Would it be correct even if it was the second mention of computers?
Would it mean that I talk about those specific computers, but just with general sense? I interpret this as they are mostly powerful, and there might be some that are not. As I understand it, saying "the computers" will imply all of them. Is having no article appropriate here or should I use "some", "most", etc., instead?
Thanks.
