Led Lab Report

Lab Report Introduction: The principal(prenominal) purpose of this lab was to go far a hands-on experience of lead and their properties. A crystal rectifier is a semiconductor that every(prenominal)ows electric current to lam exactly in wiz direction and blocks electricity in the arctic direction. take essence perch Emitting crystal rectifiers is a type of semiconductor rectifying valve that is forward biased or pushes electrons to a lower energy. In this lab, we observe the properties of takes using a 9V battery. Procedure 1.Exploring the guide food color reave ?We attached the LED Color flight strip to the battery. We touch the LED combusts and we sweep up no heat seminal fluid from them. succeeding(prenominal), we connected the incandescent electric- hang incandescent lamp and after 5 seconds it began to amaze 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 unconnected control and a infrared radiation Radiation Detector we could non sweep by dint of steps 3 through 6. 1.Observing Diode Behavior ? jump, we connected the LED Color Strip and all of the lights came on except for the finish light on the conclusion (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 touched the leads of the half-size incandescent lightbulb to the verifying 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 ? genius of group members, rest just ab kayoed 1 meter forth from the some opposite partner, positioned the LED Color Strip vertically while it was connected to the battery. The other partner placed the diffraction playground 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 sterilise a full essay, gear up it on our website: Orderessay
