What is Current Flow and LED Brightness Experiment about?
The student conducted an experiment on March 9, 2017 to test the current flow in a breadboard circuit containing three LED bulbs and resistors. The 100 ohm resistor produced the brightest bulb, the 470 ohm resistor the second brightest, and the 1000 ohm resistor the dimmest. The student found that resistors have a significant impact on bulb brightness by controlling the amount of current, and their hypotheses that resistors would not make a large impact was incorrect.
