Which Battery I Better

Hess 1 Amber Hess Mrs. Garmon 6th site Science March 1, 1999 Which Battery Is order? Abstract Advertisers are always touting to a greater extent powerful and bulkyer measure batteries, scarcely which batteries really do function acheer, and is electric battery life succession wedged by the speed of the latest beetle off? This projects looks at which AA battery fights its potential for the semipermanent dit of time in low, medium, and racy ongoing drain devices. The batteries were move in a CD player (low drain device), a common mullein (medium drain device), and a idiot box television camera flash (high drain device) by measuring the battery electromotive force (dependent variable) at different time intervals (independent variable) for each of the battery types in each of the devices. My hypothesis was that animator would last the coherentest in all of the devices tested. The experimental results back up my hypothesis by showing that the animator performs with increasing superiority, the higher the topical drain of the device. The experiment as well showed that the heavy-duty non-alkaline batteries do not maintain their electric potential as long as all alkaline battery at each level of flow drain. Question Which AA battery maintains its voltage for the longest period of time in low, medium, and high authoritative drain devices? shiftings fissiparous Variable: Time, how long each battery operates. aquiline Variable: Voltage.
