In electrical engineering, impedance is the opposition to alternating current presented by the combined effect of resistance and reactance in a circuit.

The self resonant frequency of an inductor is the frequency at which the parasitic capacitance of the inductor resonates with the ideal inductance of the inductor resulting in an extremely high impedance. At this frequency the device looks like an open circuit.
Frequency Response describes the range of frequencies or musical tones a component can reproduce. Frequency response measures if and how well a particular audio component reproduces all of these audible frequencies and if it makes any changes to the signal on the way through.

IP (or "Ingress Protection") ratings are defined in international standard EN 6529 (British BS EN 6529:1992, European IEC 659:1989). They are?used to define levels of sealing effectiveness of electrical enclosures against intrusion from foreign bodies?(tools, dirt etc) and moisture.
