Conclusions

The distribution of the galvanometer's moving-coil fluctuation energy with respect to frequency depends only on the total damping intensity of the coil.

The variance of these fluctuations does not depend on which of the above effects produces them. The share contributed to the variance of fluctuations by each effect is proportional to the ratio of each of their damping co-efficients to the total damping coefficient of the galvanometer coil.
