However, in a DC circuit this relationship is commonly calledResistance, as defined by Ohm's Law but in a sinusoidal AC circuit this voltage-current relationship is now called Impedance. In other words, in an AC circuit electrical resistance is called “Impedance”.

hi dude
Electrical impedance is the measure of the opposition that a circuit presents to a current when a voltage is applied. ... Impedance extends the concept of resistance to AC circuits, and possesses both magnitude and phase, unlike resistance, which has only magnitude.
