What is the difference between a resistor, capacitor, and inductor?

A resistor dissipates energy in the form of heat, a capacitor stores energy in the form of an electric field, and an inductor stores energy in the form of a magnetic field. Also, each of these components have different functions which play an essential role in electrical and electronic circuits.

The Fundamentals of RF Inductors

What is the Self Resonant Frequency of an inductor? Real inductors have turn-to-turn winding capacitance that acts as if it were a parallel circuit element. The self-resonant frequency (SRF) of an inductor is the frequency at which the inductive reactance is equal in magnitude to the capacitive reactance of the windings. At the SRF, the ...

23.2: Reactance, Inductive and Capacitive

Capacitors favor change, whereas inductors oppose change. Capacitors impede low frequencies the most, since low frequency allows them time to become charged and stop the current. Capacitors can be used to filter out low frequencies. For example, a capacitor in series with a sound reproduction system rids it of the 60 Hz hum.

Difference Between Capacitor and Inductor

One of the main differences between a capacitor and an inductor is that a capacitor opposes a change in voltage while an inductor opposes a change in the current. Furthermore, the inductor stores energy in the form of a magnetic field, and the capacitor stores energy in the form of an electric field.

Why does a real world capacitor behave like an inductor at …

The self-resonant frequency occurs at the resonant frequency of the ideal cap and series inductor (which form a tank circuit with near zero impedance at resonance). Once you go above resonance frequency, the series inductor dominates the impedance of the component, and the capacitor impedance is so low as to be negligible.
