## Power density versus power density spectrum

hello friends,

A little doubt while reading noise in electronic devices. Is there any difference in the physical interpretation of power density and power density spectrum.

why there is a resistance term relating the two quantities. I am discussing the case where I have to compute the resistor noise.

regards,
