1.0 Experiment repot Wind Turbine
1.0 Introduction The goal of the experiment is to build a scale model of a wind turbine that generates electricity, which will be evaluated by turning on an electronic component and measuring the current with an ammeter. The experiment started with a study of how wind turbines generate electricity and a miniature simulation using electronic components.

2.0 Wind turbine working principle Wind turbines work on a very simple principle: the wind turns the blades, which causes the axis to rotate, which is attached to a generator, which produces DC electricity, which is then converted to AC via an inverter that can then be passed on to power your home. The stronger the wind, the more electricity is generated from the motion.[1] The core component of a wind turbine is the generator which converts mechanical energy into electricity. We’ve known since the early 19th century that if you turn a conductor in a magnetic field then it creates electricity, according to Faraday’s Law. So the wind provides the movement and torque and the generator does the rest.[1]

3.0 Installation process Resistor
3.1 Installation plan The installation scheme focuses on connecting the blades to the motor in order to convert the mechanical energy of the blades’ axial motion into electrical energy inside the motor, where a conductive coil (copper coil tightly wrapped on a metal core) is quickly rotated between the poles of a horseshoe magnet and then connected to the resistors to obtain the appropriate voltage for the lamp by causing a voltage drop.

P = ??? ρ = 1.225 kg/m2 A = π x r2 = 3.14 x 0.12 = 0.031 m2 v = 0.41 m/s
Wind power = 1/2 x ρ x A x v3 = 1/2 x 1.225 x 0.031 x 2.74x10-3 = 5.21x10-5 Watt
