across a resistor through which no current is flowing, where R is the resistor's resistance, $\Delta f$ (also known as the measurement's Equivalent Noise Band Width (ENBW)) represents the range of frequencies over which you are measuring the ac voltage generated by the random motion of the electrons. Alternatively, if you prefer, you could express the relation in terms of the \textit{mean square ac voltage} $ = (4 R \Delta f) k_B T$. You would also mention that this non-zero mean square ac voltage due to thermally generated random motion of electrons is known as Johnson noise \cite{Johnson_1928}, named after the person who first discovered and measured it.   If you need to review the physics behind this, I suggest re-reading Chapter 1 of the TeachSpin manual rather than the unpublished lab report of an undergraduate from another school whose data isn't nearly as good as yours!   \textbf{Similarly, the Shot noise part of your aims section would be expected to} reference Schottky's prediction of a fundamental relation between the size of fluctuations in current If you need to review the physics behind this, I STRONGLY suggest re-reading Chapter 1 of the TeachSpin manual on JOhnson Noise and Chapter 3 on Shot noise rather than relying on the unpublished lab report of an undergraduate from another school whose data isn't nearly as good as yours!
