\subsection{Shot Noise:}  The reason we can perform the shot noise experiment is because at any given time there are different amounts of electrons within the given apparatus. For example, if you average the number of electrons on one side of a resistor and average them on the other side of the resistor, at any given second there could be an imbalance of electrons. In any electronic device, shot noise is the random fluctuations of electrons in the DC current. This happens only because current is composed of discrete amounts of electrons that can become unbalanced from one side of an apparatus to another (like a resistor). Because the amount of energy an electron carries is very small compared to most experiments, many people ignore the shot noise in their electronics. For this report, we are amplifying the shot noise in order to find the charge of the electron.   Reference: http://web.mit.edu/dvp/Public/noise-paper.pdf
