Question

Is inductance a function of frequency?

Answer 1

1. The back emf created by an inductor is equal to its inductance multiplied by the rate of change of current in the inductor, and inductive reactance is proportional to frequency ($X_{L}af$).
2. The formula of inductance in terms of frequency:
3. $X_L=2\pi f_L$, Where, $f$= Frequency and $L$= Inductance

Therefore,

1. The inductor's impedance rises as the frequency rises, while the parasitic capacitor's impedance decreases, to the point where the capacitor's impedance is even lower at any elevated frequency than the inductor's, implying that your inductor functions as a capacitor.
2. Inductors can be divided into two groups based on their function.
3. The first is used to control signals, while the second is used to store electrical energy.
4. Reactive magnetic fluxes are produced in the coil to counterbalance changes in electric current.

Hence, inductance is a function of frequency.
