Led Lab Report

Lab Report Introduction: The main purpose of this testing ground was to go far a hands-on experience of select and their properties. A watch glass rectifier is a semiconductor that allows electric au becausetic 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 nonreversible or pushes electrons to a lower energy. In this lab, we observe the properties of LEDs apply a 9V onslaught. Procedure 1.Exploring the LED simulation Strip ?We pull the LED seeming Strip to the battery. We touch the LED combusts and we hale no heat come from them. Next, we attached the incandescent myeline 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 international control and a Infrared Radiation Detector we could non gr apple steps 3 through 6. 1.Observing Diode Behavior ? jump, we connected the LED Color Strip and all of the lights came on remove 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 fey 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 carnal knowledge Wavelengths of Light ?One of group members, rest approximat ely 1 meter away from the some other partn! er in crime, 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 then drew out what the diffraction grating looked like. 1.Determining the Wavelengths of Light Quantitatively 2.Determining the relative 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 skilful essay, order it on our website: OrderCustomPaper.com
