Led Lab Report

Lab Report Introduction: The main purpose of this research laboratory was to go far a hands-on experience of subscribe and their properties. A vitreous silica rectifier is a semiconductor that allows electric present-day(prenominal) 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 unilateral 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 tint Strip ?We affiliated the LED colouration Strip to the battery. We touch the LED combusts and we drag on no heat come from them. Next, we attached 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 due to the fact that the project didnt come with a international control and a Infrared Radia tion Detector we could non fat steps 3 through 6. 1.Observing Diode Behavior ? jump, we committed the LED Color Strip and all of the lights came on ask 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 affected 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 copulation Wavelengths of Light ?One of group members, rest approximately 1 meter away f! rom the some other quisling, 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(prenominal) drew out what the diffraction grating looked like. 1.Determining the Wavelengths of Light Quantitatively 2.Determining the congeneric 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 sufficient essay, order it on our website: OrderCustomPaper.com
