             0 cell = intensity about  10
         1 cell =     "       "    20

  1. As the battery power was increased the pitch of S became lower       from the pitch when no battery was employed to that when 5 cells were used ­ the difference was a whole tone.
  2. Effect of Intensity Battery + Quantity Battery. Circuit as in last experiment
             2 cells arranged for intensity = 22
         2 cells     "     "  quantity  = 22
         5 cells     "     "  intensity = 17
         5 cells     "     "  quantity  = 17
    Estimate of the loudness of the resulting sound at M2 The loudness of the sound where no battery was employed being called 10.
  3. The spring S (Fig1) was removed +
