How does an increase in frequency typically affect inductance?

Inductance is a property of an electrical component (usually a coil or inductor) that describes its ability to store energy in a magnetic field when electrical current passes through it. The relationship between frequency and inductance hinges on how inductors behave in alternating current (AC) circuits.

As frequency increases, the reactance of the inductor also increases, given by the formula (X_L = 2\pi f L), where (X_L) is the inductive reactance, (f) is the frequency, and (L) is the inductance. Inductance itself, which is determined by the physical characteristics of the inductor such as the number of turns, core material, and geometry, remains constant and is not directly affected by frequency in an ideal sense.

However, in practical applications, various factors can influence the effective inductance at high frequencies, such as parasitic capacitance and core losses, which can lead to a reduction in the perceived inductance at very high frequencies. This can create the scenario where the effective inductance appears to decrease with an increase in frequency under certain conditions, particularly in non-ideal inductors.

Thus, understanding that effective inductance may decrease due to high-frequency effects makes
