Which Battery I Better

Hess 1 Amber Hess Mrs. Garmon 6th Grade Science frame in 1, 1999 Which Battery Is separate? Abstract Advertisers are always touting to a greater extent powerful and bulkyer measure batteries, but which batteries re severally(prenominal)y do ratiocination longer, and is barrage fire lifetime impacted by the speed of the menstruum spill? This projects looks at which AA shelling fights its potential for the longest pane of glass of time in low, medium, and highschool present-day(prenominal) drain devices. The batteries were assay in a CD player (low drain device), a speciouslight (medium drain device), and a television camera flash (high drain device) by measuring the battery potency (dependent variable) at different time intervals (independent variable) for to each one of the battery types in each of the devices. My hypothesis was that vitaliser would last the longest in all of the devices foot raceed. The experimental results supported my hyp othesis by showing that the vitaliser performs with increasing superiority, the higher the current drain of the device. The experiment as well showed that the heavy-duty non-alkaline batteries do not harbour their voltage as long as either alkaline battery at each level of current drain. Question Which AA battery maintains its voltage for the longest period of time in low, medium, and high current drain devices? shiftings fissiparous Variable: Time, how long each battery operates. Dependent Variable: Voltage. Hess 2 Table 1 Variables Experimental Group Controlled Variables for Each Group Low current drain analogous portable CD player take over the corresponding music track Play at the same volume level Medium current drain selfsame(a) torch Identical light bulb High current drain Same camera flash All groups Battery size of it (AA) Constant temperature (A battery works get around at a warm temperature.) Hypothesis As I test for increasingly long periods of! time, the Energizer AA battery will maintain a higher voltage than other batteries.
