Lab 5: Solar Cells

What color light do you think generates the most voltage? ; Source: FreeStockPhotos.biz

 

Objective:

Solar energy is a type of renewable energy that can make your lifestyle more sustainable, especially if you are looking to reduce your footprint. In fact, you may have seen solar panels on homes in residential areas – these panels collect solar energy from the sun and convert it into solar power to power our homes, any excess any is either fed back to power grid or even sold back to power companies. In lab 5, we had the opportunity to take solar energy into the laboratory setting by introducing a new piece of equipment, the NXT with a light sensor. The goal of the lab is to gain hands-on experience on observing how solar energy is absorbed when manipulated in a lab setting.

Lab 4: Experimenting with a Generator

Michael Faraday, scientist. (1791-1867)/ Wikipedia[2]
Objective:

In experiment 4 we applied the concept learned in Faraday’s Law of Induction “[which] describes how an electric current produces a magnetic field and, conversely, how a changing magnetic field generates an electric current in a conductor”[1] In this lab, the main piece of equipment will be a tube that resembles a flashlight and we will observe that as the magnet inside the tube is shaken faster, the greater voltage there will be.
