How does resonance affect the strength of an acid?

If there is resonance than this increases the stability of the molecule. Therefore, due to resonance and delocalization of the electrons, the more readily the molecule will give off H+ and be a stronger acid.

Resonance stabilizes anions by delocalizing their negative charge. By creating a more stable resulting anion, the relative acidity will increase. Dr. Lavelle stated during lecture that the two things that make an acid a strong acid is: 1. the acid loses H+ easily and 2. the resulting anion must be stable. Resonance goes with the second property that makes acids stronger(more acidic)

If an acid's corresponding conjugate base depicts resonance, it means that the resulting conjugate base is a more stable molecule, thus meaning that the original acid is a strong acid.
