ENERGY AND ELECTRICITY

FORMS OF ENERGY
1. MAGNETIC
  1. MAGNETS AND ELECTROMAGNETS
2. KINETIC
  1. THE ENERGY IN MOVING OBJECTS
3. HEAT
  1. THERMAL
4. LIGHT
  1. RADIATION
5. GRAVITATIONAL POTENTIAL
  1. STORED ENERGY IN RAISED OBJECTS
6. CHEMICAL
  1. FOOD:FATS
7. SOUND ENERGY
  1. ENERGY IS RELEASED IN VIBRATING OBJECTS
8. ELECTRICAL
  1. ENERGY IN MOVING OR STATIC ELECTRICAL CHARGE
9. ELASTIC POTENTIAL
  1. ENERGY STORED IN STRETCHED OR SQUISHED OBJECTS
10. NUCLEAR
  1. STORED IN THE NUCLEAS OF ATOMS
DEFINITION OF
1. VOLTAGE
  1. THE AMOUNT OF PUSH A CELL OR BATTERY HAS
    1. POTENTIAL DIFFERANCE BETWEEN VOLTAGE LEVELS BEFORE AND AFTER A RESISTOR OF SOME SORT
      1. HARD TO PASS THROUGH SOMETHING E.G. LIGHT BULB
  2. VOLTS IS THE MESUREMENT
2. CURRENT
  1. HOW EASY IT IS TO PUSH THE ELECTRONS ROUND A CIRCUIT
DIFFERENT CIRCUITS
1. PARALLEL
  1. BULBS HAVE THERE OWN SEPERET CIRCIUT IN THE CURCIT
    1. BULBS ARE ALL THE SAME BRIGHTNESS
      1. IF ONE BLOWS THE OTHERS WONT AS IT ISNT THE MAIN CIRCIUT PART
2. SEIRES
  1. ALL THE BULBS ARE ON THE SAME LOOP
    1. CAUSES DIMMER SECOND BULB
      1. AS THE ELECTRONS HAVE GOT HALF THE ELECTRICITY THEY STARTED WITH
        IF ONE BLOWS THEY ALL BLOW AS THE ELECTRONS NEED TO PASS THROUGH ALL THE BULBS TO COMPLETE THE CIRCUIT
3. CELL IS A SINGLE BATTERY
EQUATIONS
1. THE TRIANGLE
  1. V=I X R
  2. R = V/I
  3. I= V/R
2. OHMS LAW
  1. V = IR
METHODS OF ELECTRICITY GENERATION
1. WIND
  1. TURBINE
2. HYDROELECTRIC
  1. GEP
3. WAVE
4. NEUCLEAR
  1. BOOM!
5. SOLAR
  1. PARALEL PHOTOVOLTIV CELL
6. FOSSIL FUELS
  1. POLLUTION
7. BIOMASS
  1. MAKES STEM TO POWER TURBINE
  2. WOOD, DUNG
8. GEOTHERMAL
  1. HEAT FROM THE EARTH
THE ELECTRICITY NETWORK
1. FROM PLANT
  1. TO TRANSFUSER
    1. TO NATIONAL GRID
      1. TO OUR HOMES
        TO OUR APPLIANCES
        (ALL APPLIANCES WILL ALSO HAVE A TRANSFUSER IN TOO)
    2. (MAKES IT SAFE)
ENERGY CHANGING
1. A LIGHT BULB MIGHT CREATE 10% LIGHT ENERGY BUT 90% HEAT ENERGY
  1. THIS WOULD BE LESS EFFIECENT
  2. COMMENLY HEAT IS THE WASTE PRODUCT
2. WE SHOW ENERGY USES IN A N ENERGY FLOW DIAGRAM
