Noise
An unwanted voltage fluctuation generated within the resistor. Noise is any any spurious variation in the electrical output not present in the input. Total noise of a resistor always includes Johnson noise which is dependent only on the resistance value and temperature of the resistance element. Depending on the type of element and construction, total noise may also include noise caused by current flow, and noise caused by cracked bodies and loose end caps or leads.
