• The vibrations of the electrons cause an electric signal
across the terminals of the component. This electric
signal is called noise or thermal noise.
5. Frequency Response:
• The frequency response of a resistors is the frequencies
the resistors will work as a pure registers without any
significant effects associated with other component.
• Frequency response of wire wound resistors is high so, it
is used in high power application.
6. Stability :
• Stability defines the long term variations of the
resistance. After a long duration of electric load,
resistance value will not vary much.
