Impedance vs admittance.

It could be said that electrical resistance is the opposition to steady electric current. An ideal resistance does change with frequency when connected with DC. Impedance is the measure of the nature of opposition of the AC electricity which is created due to inductance and capacitance. This opposition varies with the frequency.
