This is the parallel circuit we created for dim light celebration. hooray!!
For this lab we had to determine the change in temperature using the given voltage output and charge density of nicromium. we did this by manipulating the power formula to obtain the current. from this we were given uncertainty in the mass of water and voltage. using these uncertainties we calculated the uncertainty in current and in change in temp. With this uncertainty the experimental value was not within our uncertainty. This could be due to the charge density used for our calculations where other groups differed.
This is the graphical result from the experiment where we found change in temp over 10 min. the blue graph represents the results for doubling the voltage where we saw that the change in temp did not double but increased by a factor of four. this could be shown from the above picture where the formula for change in temp, V is squared.
This is our results from experimenting with electric potential where charges were moved and added. Here we had to wrap around the thought of negative and positive electric potential energy.
To finish the class we showed how hot dogs carry current and to prove that leds were lit by placing them in the hotdog. Also with the hot dog experiment we say that the greater the distance between the led legs the brighter the light due to a higher change in electric potential.
