DbDb Major
Augmented Dbaug has a raised 5th. As a dominant it resolves up a 4th — the raised 5th rising a semitone. Returning to the major of the same root, it instead falls back to a perfect 5th.
Other resolutions

Deceptive resolution
DbmDb Minor
An augmented chord can resolve to the minor chord of the same root: the raised 5th falls to a perfect 5th and the major 3rd lowers to a minor 3rd.

No resolution needed
In a whole-tone context, the augmented chord can be used as a color chord — without mandatory resolution.
Dbaugsource
Jazz reharmonization
GbGb Major
In jazz, aug often acts as a dominant with raised 5th, resolving up a 4th as a V7 substitute.

Functional resolution
FF Major
Due to its symmetry (equal intervals), an augmented chord can resolve to chords a major 3rd apart.
Bbmharmonic minor
Dbaugdegree III
The raised 7th of harmonic minor makes the III triad augmented — Dbaug arises within the key on its own.
DbaugV+
F#resolution
As a dominant it resolves a fourth up: the raised fifth (A) rises a semitone into the tonic's third (Bb).
