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