It's not measured in resistance but in impedance. It may have some high resistive value but this is not it's major effect. A capacitor in series can couple an AC signal from point A to point B while blocking DC. A capacitor from some point to ground can remove or reduce an AC component from that point. This filters or "smooths" the signal. A capacitor and resistor circuit will have a specific time constant (TC) to charge or discharge and can provide timing signals. A capacitor will also produce a condition where the current leads the voltage by some degree. A capacitor is a reactive device, not resistive. It’s not measured in resistance but in impedance.
