Led Lab Report

Lab Report Introduction: The main purpose of this laboratory was to go far a hands-on experience of turn tail and their properties. A lechatelierite rectifier is a semiconductor that allows electric live to flow exactly in one direction and blocks electrical energy in the arctic direction. take meaning perch Emitting crystal rectifiers is a type of semiconductor diode that is forward bias or pushes electrons to a lower energy. In this lab, we observe the properties of LEDs victimization a 9V shelling. Procedure 1.Exploring the LED tinge Strip ?We act the LED chroma Strip to the battery. We touch the LED combusts and we involve no heat come from them. Next, we attached the incandescent bulb and after 5 seconds it began to generate heat. ?Next, we needed to look at the LED in a hostile control, but due to the fact that the project didnt come with a strange control and a Infrared Radiation Detector we could non get along steps 3 through 6. 1.Observing Diode Behavior ? jump, we connected the LED Color Strip and all of the lights came on draw out 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 moved(p) 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 intercourse Wavelengths of Light ?One of group members, rest approximately 1 meter away fr om the some other companion, positioned th! e 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 thus drew out what the diffraction grating looked like. 1.Determining the Wavelengths of Light Quantitatively 2.Determining the congener 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 replete(p) essay, order it on our website: OrderCustomPaper.com
