What is Electricity?  Electricity is a form of energy that is created by the flow of electrons

Electricity from power plant to customer

Power Plant to Customer  First electricity is generated at a power plant, wind farm, or generating station  Voltage of electricity is increased at the voltage station  Electricity is transferred across transmission lines  The voltage of the electricity is decreased at the local transformer station  Electricity is carried to your neighborhood on power lines  Before entering your home the voltage is decreased on the pole transformer on your house

How is electricity created?  In an atom there are protons and electrons, normally the number of negatively charged electrons is equal to the number of positively charged protons  If an atom looses a proton or electron an electric current is produced

Words to know  Electricity: a form of energy resulting from the existence of charged particles.  Circuit breaker: an automatic device for stopping the flow of current in an electric as safety measure.  Fuse: a safety device consisting of a thin strip of metal that melts and breaks an electric circuit if the current exceeds a safe level.

Words to know  Surge protector: electrical device inserted in a power line to protect equipment from sudden fluctuations in current.  Solar flare: a brief eruption of intense high- energy radiation from the sun’s surface.  Kilowatt: is the units for electricity (1,000 watts)  Static Electricity: the build build up of electrical charge that remains on an object

Words to Know  Charged particles: particles that conduct electricity  Atoms: the smallest form of a chemical element, all matter is made up of atoms  Circuit: a loop that conducts electricity in which all components are liked together  Terminal: place for attachment for wires to battery

Parallel Circuit  Parallel Circuit's: an element off an electrical circuit when components are connected and parallel so that the same voltage is applied to each part of the circuit

Circuit Breakers, Fuses and Surge Protectors  Surge protectors allow power to be removed without interrupting power of other devices  If a component fails inside the protector only the protectors breaker will fail not the other loads  Circuit breakers protect an electrical current form damage or over load  Fuses are used in cars, computers and most major appliances  They protect the wires transmitting an electrical current

Electric Meters  A device that measures the amount of electric energy consumed by a business or residence; even an electric powered device

Cost  You are billed every month for electricity based on how much you use  Fuel costs, capital costs, and other factors such as waste are taken in account in someone’s electric bill

Series vs. Parallel Circuits  Two of the simplest components in an electrical circuit  A series circuit is composed and connected in a series  However, one connected completely in parallel is called a parallel circuit

Alternating Current Vs. Direct Current  Alternating  Safe to transfer over long city distances  Electrons change directions  Reverses direction when flowing in a circuit  Direct  Voltage of current can not travel long distances until it starts to loose energy  Electrons move move consistently in a forward motion  Flows in one direction in a current

Batteries In electricity, a battery is a device consisting of one or more electrochemical cells that convert stored chemical energy onto electrical energy electricity. Batteries have become a common power source for many household and industrial appliances. There are primary batteries which are only to be used once and secondary batteries which can be recharged.
