THIS WOULD BE AN EXCELLENT PLACE TO INTRODUCE equations \ref{eq:NyquistPredictionForJohnsonNoise}or \ref{eq:boltzmann}.   Therefore, larger resistances would generate more noise because the electrons carry more energy (???) (??? not true!)  and in turn create a higher fluctuation in voltage. In order to understand Johnson Noise, imagine that a resistor is filled with electrons. At anytime the electrons are bouncing off or scattering off each other. This means that at any given time, there will be an imbalance of electrons from one side of the resistor to the other. This imbalance of electrons results in a difference of electric potential across the resistor, which is noise. Reference: http://web.mit.edu/dvp/Public/noise-paper.pdf
