\section{Johnson Noise}  To perform the detect  Johnson Noise Experiment, in order to find the Boltzmann constant,  we used the Noise Fundamentals devices and two digital multi-meters. We did collected  two trials, sets of data,  one with a $10K$ ohm resistor, and one another  with a $1K$ ohm resistor. resistor, to make sure our data is consistent, to see the dependence of Johnson Noise on resistance, and to obtain a comparatively more accurate and precise value for the Boltzmann constant.  We also did an experiment on collected data using  a $1$ ohm resistor in order resistor. Since the resistance is so small that the Johnson noise is much smaller than the instrumental noise, we were able  to find the noise in the apparatus used. to be subtracted out of our data for the $10k\Omega$ and $1k\Omega$ resistors. This will give us a more accurate result.
