V_{\textrm{Johnson noise, RMS}} = \sqrt{} = \sqrt{(4 R \Delta f) (k_B T) }
\end{equation}
where $R$ is the resistance of the
resistor, conductor, $\Delta f$ is the equivalent noise bandwidth (ENBW), $k_B$ is the Boltzmann constant (what we are
hoping trying to
reproduce), find), $T$ is the temperature of the
room, conductor, and $\sqrt{}$ is the measured
voltage from the preamp. voltage.
The %The ENBW is what we use to represent the frequencies we use in order to vary the ac voltage that is generated from the random fluctuations of electrons within the resistor. We will be measuring the $\sqrt{}$, the $\Delta f$, the $T$, and the $R$ in order to find the $k_B$.
