\section{Experiment on Johnson Noise}  \subsection{Method for Johnson Noise}  In order to get the desired data, we decided to vary $\Delta f$ in order to vary the bandwidth. To do this, we kept the resistance ($R$) constant, but did three different trials where each trial had a different $R$ value. The values for $R$ are as follows: $10 \textrm{ k}\Omega$, $1 \textrm{ k}\Omega$, and $1 \Omega$. As with any resistor, there is error in the measurement and Table \ref{table:True_Resistance}, shows the true, measured value of the resistance. You can perform the Johnson Noise experiment by varying resistance for a given bandwidth ($\Delta F$), but we chose to vary $\Delta f$ and keep resistance constant.
