ELECTRICITY CURRENT PRESENTATION MADE BY: MASON, CARLOS, ANDREW GROUND WIRE Ground wire- a wire that is connected to the earth to lower the risk of electrical shock. Protects against electrical shocks. The yellow wire connected from the power pole to the ground VOLTS, AMPS, AND WATTS Volts- is measured in volts. Ampere- is a unit of measure of the rate of electron flow of one coulomb per second. Watt- is the SI unit of power, equivalent to one joule per second. CURRENT ELECTRICITY Current electricity- is the flow of electrons in a certain path to create electricity. THE DIFFERENCE??? The difference between static electricity and current is, static electricity steals electrons and only has one path. Current electricity has multiple paths and doesn’t steal anything. ADVANTAGES/DISADVANTAGES Advantage to series circuit is there is only one switch to turn on and off. The circuit is broken. Disadvantage is if one goes out they all go out. Advantage to parallel is if one goes out there is still electricity being produced to the rest. Disadvantage is there is more than one switch. Series Circuit Parallel Circuit ELECTRICITY BEING GENERATED • There are many ways electricity can be produced. • Windmills • Nuclear fueled power plants • Power stations • Turbines • Dams • Generators DAMS AND WIND TURBINES Dams and wind turbines produce kind of in the same way. When the wind and water flows its kinetic energy. That kinetic energy is converted into electricity. NUCLEAR FUELED POWER PLANTS In a power plant water is turned into steam, and that steams turns the turbine generators to produce electricity. To cause the water to steam they use uranium atom to split the atoms called fission. GENERATORS AND POWER STATIONS Electricity is mostly generated at a power station by electromagnetically generators, primarily driven by heat engines fueled by chemical combustion or nuclear fission. Generators convert mechanical energy into electricity. Power station Generators HEAT A resistor turns the electricity into heat and slows down the current. Light bulbs are resistors.
