Learn MoreAnd "resistance" refers to impeding the flow of a DC current. In capacitors the main function is impeding the flow of audio (AC) currents and in that case "resistance" is termed "impedance". The interesting thing about impedance is that unlike DC resistance it changes with frequency. That is one reason capacitors are useful.
