Electrical Power Generation from Environmental Constraints
- 2. Electricity by definition is electric current that is used as a power source! This electric current is generated in a power plant, and then sent out over a power grid to your homes, and ultimately to your power outlets.
- 3. The movement of charges such as electrons is called current, and this electrical current is what powers household appliances. Electric Current = Charge Passing Through A Given Area ------------------------------ - Time
- 4. An easier way to think of electric current is to picture cars going through a Turnpike or Parkway Toll. The cars could represent electrons or charge, and the toll booth could represent the cross sectional area of the wire at a certain point. If you counted the number of cars or electrons, that passed through the toll booth or a certain cross sectional area of the wire, and divided that number by the time it took for those cars or charges to pass, you would get the current!
- 5. Electric current generation - whether from fossil fuels, nuclear energy, renewable fuels, or other sources is usually based on the following Equation: So How An Electric Current is Generated ? Simple Equation For Electricity Generation
- 6. In September of 1831, Michael Faraday made the discovery of Electromagnetic Induction. Faraday attached two wires to a disc and rotated the disc between the opposing poles of a horseshoe magnet creating an electric current. What does copper wire and magnets have to do with Electricity ?
- 7. An electric current is not generated unless the magnetic field is moving relative to the copper wire, or the copper wire is moving relative to the magnetic field. If you place a magnet and a conductor (copper wire), in a room together there will be no electric current generated. This is because motion, from our equation for electricity, is missing! Motion is Essential !!
- 8. •The major problem in electricity generation Is where does the Motion come from that keeps the copper wire and magnets moving relative to one another. In this case, wind power applies a force to the blades that turns them. • The spinning blades, spin an armature that turns the copper wire relative to the magnetic field. As long as the blades spin, electricity will be generated!
- 9. - AC of 60 Hz produced by generator - Resistance losses are smallest at high voltages and low currents
- 10. At home, electric current that was generated by generators in the power plant is used to power electric appliances. The electric current, running through the copper wire causes the armature to spin which is how most motors generate motion.
