Few weeks ago, my team and I came up with an idea of how to proof some of the concepts that we have learned throughout this semester. You may remember that we want to use a wind turbine to test the relationship between power, wind speed and surface area. We will also like to use the basics of Ohm’s Law, power, and efficiency to obtain more information out of our measurements.
Initially we intended to simulate the power and electricity generation by lighting up several types of LED’s. Unfortunately, this was not possible since the amount of voltage and current coming out of our wind turbine was not enough to light them up. So instead of coming up with a crazy circuit configuration that will probably take some time to conned and assemble, we decided to stay with basics: We will use a multimeter to obtain several measurements and use some formulas to obtain more values. Once we have all these values we will be able to compare them and hopefully confirm that our values follow the concepts and laws that we have learned throughout this semester. Below is an image that provides a shot review of how wind turbines generates electricity.
