# Estimation of dipole moments in aromatic compounds

If it asks to compare dipole moment in aromatic compounds then do we see inductive or resonance effects or do we see a mix of both?

E.g. we have to compare dipole moment in pyrrole and furan then in one we have opp direction of dipole moment in both why? Like it's a specific question but I wish to understand the mechanism behind every such tricky question so that I can do on my own.

Or suppose we have ortho hydroxyphenol then what would I say the direction of dipole moment would be? Would it be inwards towards benzene or outwards towards $$-\ce{OH}$$ group. It's not because of convention doubt, but like whether it's the resonance effect that dominates which would result in majorly + on $$-\ce{OH}$$ group and - on $$-\ce{Ph}$$ group or is it the inductive effect dominating which would result in opposite sign.
