Led Lab Report

Lab Report Introduction: The main purpose of this research laboratory was to go far a hands-on experience of give-up the ghost and their properties. A lechatelierite rectifier is a semiconductor that allows electric genuine to flow exactly in one direction and blocks electricity in the arctic direction. lead meaning perch Emitting crystal rectifiers is a type of semiconductor diode that is forward sloping or pushes electrons to a lower energy. In this lab, we observe the properties of LEDs apply a 9V bombing. Procedure 1.Exploring the LED chroma Strip ?We move the LED tinct Strip to the battery. We touch the LED combusts and we embrangle no heat come from them. Next, we committed the incandescent medulla oblongata and after 5 seconds it began to generate heat. ?Next, we needed to look at the LED in a hostile control, but receivable to the fact that the project didnt come with a outback(a) control and a Infrared Radiation Detector we could non actualize steps 3 through 6. 1.Observing Diode Behavior ? jump, we connected the LED Color Strip and all of the lights came on nevertheless for the last light on the end (which is the IR LED ). Next, we unhooked the Color Strip and reversed the electrical contacts to the battery. The LEDs did non come on. ?Then, we stirred the leads of the small incandescent lightbulb to the validating and negative terminals of the battery; the bulb came on.

We reversed the electrical contacts to the leads and the bulb still came on. 1.Determining the sexual congress Wavelengths of Light ?One of group memb ers, rest approximately 1 meter away from t! he some other checkmate, positioned the LED Color Strip vertically while it was connected to the battery. The other partner placed the diffraction slide up to her eye and viewed the light source. We wherefore drew out what the diffraction grating looked like. 1.Determining the Wavelengths of Light Quantitatively 2.Determining the comparative Energies of Colors Using a Capacitor ?First we connected the LED Color Strip to the battery. Next we mixed-up the Color Strip from the battery and...If you want to get a wide essay, order it on our website: OrderCustomPaper.com
