In the light emitting diode experiment, the team used a resistor measuring 100ohms, a 3 volt diode and two AA batteries measuring 3.23 volts. The experiment used a 100ohm resistor to decrease the voltage along a circuit to light a 3 volts LED. By creating the loop this way, the diode would not bun out.
SEEII was easier than SEEI because of the acquired knowledge about circuits, electricity, volt and measurement/conversions. Once we figured out the loop, measured the resistance, double checked the specifications of the diode and which way the diode had to be positioned to emit a light, the rest was easy. Combing the 100ohms with a 3.2 volt battery dropped the volts by 1.33.
