Thermal noise that occurs in resistors. The rms noise voltage of a resistor is given by √(4
kTRB) where
k is
Boltzmann's constant,
T is the abolute temperature,
R is the resistance and
B is the bandwidth in Hertz.

In electronics, Johnson Noise is unwanted voltage variations which manifest in a receiver as noise and in other types of apparatus as spurious signals in the output. Johnson Noise is due to the random motion of electrons in a conductor, which increases with temperature.
