How a generator works Physics 1010 M.W.F. Jordan Roe David Schaffer Electric current is the flow of charge pressured into motion by voltage. Electrons in wires are conductive electrons that can be influenced to move either by being pushed or driven. When there is potential differences charged electrons flow. The flow creates an electric charge, but without potential difference there would be no charge. The rate in electrical flow is measured by amperes, amperes can be easily doubled by having a cross section of two wires in the influence of potential difference. Voltage makes electric pressure and helps move the electrons through a circuit. Electric resistance defines the conductive properties and potential flow of charges. Resistance of a wire depends not only on its conductive material properties, but also on its length and width. Thick is less resistant then thin and longer is more resistant then short. Electric resistance is measured by ohms Ω. Named after George Simon Ohm, who discovered important relationships with voltage, current, and resistance. Ohm’s law is the current in a circuit is proportional to voltage across the circuit and proportional to resistance in a current. Meaning Current=Voltage/Resistance with a constant resistance, current and voltage are the same. Increasing current increases voltage, but increase the resistance will decrease the voltage a current. Generators are machines that produce electrical current either by using a stationary magnetic field with a rotating coil or a moving magnetic field with a stationary wire. We now know that potential difference makes electricity change. Difference in magnetic fields can create potential difference in a wire, making electromagnetic induction that will create voltage and current. Introducing a magnetic field near or threw a wire will create a voltage. Meaning Voltage induced~area of loops x ∆magnetic field/∆time. Faraday’s law of inducing of electric field. Maxwell’s law show that the best way of direction of induced magnetic field and electric field are right angles. My generator has a stationary cross over wires and a rotating magnetic field. My magnetic field was connected to chain that connected to bike peddles. I spun the bike peddles to create potential difference and electric induced magnetic field. The faster I spun the higher the voltage got. The highest voltage I obtained was 1.6V. The most led lights I demonstrated was 3 even though it was very brief I still am proud of it. This experiment sounded easy to me at first, but ended up being a big pain in the butt sometimes. The experiment was worth it though I enjoyed making electricity on my own. It is something I will never forget about.
