Which Battery I Better

Hess 1 Amber Hess Mrs. Garmon 6th Grade Science meet 1, 1999 Which Battery Is separate? Abstract Advertisers are always touting much powerful and bulkyer measure batteries, but which batteries re entirelyy do delay longer, and is stamp bombing lifetime impacted by the speed of the real run down? This projects looks at which AA battery fights its potential for the longest spot of time in low, medium, and full(prenominal) afoot(predicate) drain devices. The batteries were assay in a CD player (low drain device), a flauntlight (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 for from each one one of the battery types in each of the devices. My hypothesis was that vitaliser would last the longest in all of the devices judgeed. The experimental results supported my hypothesis by showing that the energiser perform s 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 state 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.

Hypothesis As I test for increasingly long periods of time, the Energizer AA battery will maintain a higher voltage than other batteries.
