In a circuit containing a capacitor and an AC source, the current is zero at the instant the source voltage is maximum. Is it consistent with ohm’s law?

when only a capacitor is atached to the ac source the current and emf have a phase difference of (pi/2) i.e.90degree therefore i=imax(sin wt) while emf =emax(sin wt+(pi/2)) while this circuit not having any resistance not follow ohm's law
