Final answer:
Inductive reactance (XL) and capacitive reactance (XC) are the impedance components that are inversely related and are dependent on frequency as well as the circuit's inductance and capacitance.
Step-by-step explanation:
The two components in impedance that are inversely related are the inductive reactance (XL) and capacitive reactance (XC). These components are dependent on the frequency of the alternating current (AC) and the values of the inductance and capacitance in the circuit.
While XL is directly proportional to the frequency (and the inductance), making it increase as the frequency increases, XC is inversely proportional to the frequency (and directly proportional to the capacitance), meaning that it decreases as the frequency increases. Because of these opposing relationships with frequency, inductors and capacitors can partially to totally cancel each other's effect in an AC circuit, which is especially evident at the circuit's resonant frequency where XL exactly equals XC.
