When you use it
Use it when you must choose between pairs such as he or him, we or us inside a sentence. The nominative case marks the subject, and the accusative case marks the object of a verb or the object of a preposition.
Watch out
In a pair such as "You and he", the pair is the subject, so use the nominative form and never "you and him". The case depends on the job the pronoun does in the sentence, not on where it stands.
