The difference between "rest" and "other" in sentence
Which one is more correct:
"Rest of the transformers" or" other transformers"
For example when you report about a hundred transformer and you want to exclude someone out of the others which one is better to use.

Question

Answer

The rest of the transformers . . . (You need the article 'The' otherwise it would be incorrect)
The other transformers . . . 
Other transformers (this would work as well) . . . 
One of the transformers . . . 
Some of the transformers . . . 
Many other transformers . . . 
A few transformers . . .

Answer

Not as much "rest" and "other" help you to exclude someone as the context. You can say: "...one transformer/several transformers did something and/but the rest of the transformers didn't..." or "...one transformer/several transformers did something and/but the others/ the other transformers didn't...". Both words you have to use with "the" anyway, "the rest" - it's always like that and "the other" means you separate that one or the group.

Answer

In this situation, 'rest of the transformers' is a better option because it deals with a definite number of things (a hundred transformers here).  'Other transformers' is a more general expression.
