doug. that is one kind of noise.
i mean does it have another kind of noise?

The usual measurement of random (white) noise has the dimensions of voltage per root hertz (V/√B where B is bandwidth) and is calculated as
En = √(4kTBR) where T is temperature (in Kelvins), k is Boltzmans constant (1.3807x10^(-23) J/K), B is bandwidth, and R is resistance.
As you can see, if the measurement bandwidth, temperature, and resistance remain the same, the noise will remain the same.

Higher the voltage, higher the current. From where the random noise is entering? Your question is not clear. Kindly repost.

connected in series with something a resistor does just dat slows down or resistes current the temp of the resistor rises according to how much current is applied
