4/9/2014 Quiz & Electric Potential

Quiz

In this quiz, we got assign to do the most brightest lighting system.  We put batteries in series and light  bulb.  

Redraw the diagram by using specific symbols.   

Electric Potential 

The experiment that set-up in which 200 grams of water was placed in a cup along with a coiled wired heater. The length of coiled wire in the heater was 42 cm. It was attached to a 4.5 V battery and placed in the cup of water for a total of 10 mins. A temperature probe placed inside of the cup recorded the temperature as it changed in logger pro. During the 10 mins the "heater" was submerged in water we calculated what the temperature change of the water should be given the length of the wire, voltage of battery, mass of water, and any necessary constants.

Calculating the uncertainty

the temperature change results from logger pro for each experiment. The blue data set was the 9.0 V experiment and the red data set was the initial 4.5 V experiment.
