Capacitive and inductive reactances are not real, frequency-independent resistances like ohmic resistances, but frequency-dependent imaginary resistances.
Reactances are frequency dependent and together with an ohmic resistor they form the impedance. Depending on whether it is a capacitive or inductive reactance, the reactance increases or decreases with frequency. The inductive reactance increases linearly with frequency, whereas the capacitive reactance decreases inversely proportional with frequency.phase in frequency-dependent reactances, no electrical energy is converted to heat. However, since the current flow is limited by the reactances, their behaviour is comparable to that of an ohmic resistor; they are therefore also referred to as imaginary resistors.
