Day 13

In Class Quiz

In this quiz, we were assign to establish a dim lighting system.

 

After redoing the experiment, we found a method in which lighting in the light bulb was at the most dim.  This was done by setting the battery parallel to one another and creating a circuit between thus having a higher resistance as voltage traveled toward the light bulbs. 

 

 

This is a diagram of the light bulb quiz after being redone.

4.5 V compared to 9 V

The above graph displays in blue the 9 V and red 4.5 V emitted into water with the change in temperature.

The above picture displays our calculations for the 4.5 V.

This is a picture of our 9 V Calculations

This picture displays our percent uncertainty of change in temperature.  It was deduced that the current value obtained from the other group, 8.9 A, was wrong since it did not match our experimental values.
