The quiz set up that me and my group did. My team was assigned to make the set up as bright as possible with the given materials, unfortunately we did the opposite which is to make it as dim as possible.
Graph to show changes in the temperature of water. Blue used a higher voltage than the red
For the first experiment with using 4.5V the change in temperature was 2.45 +/- 1.25 degree C/ kelvin
For the second experiment with 9V the change in temperature was 9.79+/- 5.00 degrees C/ Kelvin. A person would guess that doubling the voltage would double the change in temperature but this it not the case it is roughly 1: 5. This could be from the the greater difference between the voltage and the resistance in the wire. This gap increased the power with in turn increased the change in t temperature
A demonstration for the cooking forhotdog experiment made by the professor. The larger the gap between the anode and cathode the brighter the LED
