Translate am: "Wetin dem dey call the effective resistance of an electrical circuit to alternating current? Based on the question wey dey above, write small tori wey contain the answer. E fit be 1 - 20 sentences. Context:" <response>: ```where one prime dey show di real part and two prime dey show di imaginary part, Z(ω) na di complex impedance with di dielectric dey present, Ccmplx(ω) na di so-called complex capacitance with di dielectric dey present, and C0 na di capacitance without di dielectric. (Measurement "without di dielectric" for principle mean say measurement for free space, wey be goal wey no fit achieve as even di quantum vacuum dey predict to show nonideal behavior, like dichroism. For practical purposes, when measurement errors dey taken into account, often a measurement for terrestrial vacuum, or simply a calculation of C0, dey accurate enough.)```
