  • 1. Electrical Fruits Phy 350 project *maryam ariffin *ain norin
  • 2. AIMS
  • 3. To observes the freshness of fruits affect on voltage and pHTo determine which fruits provide highest voltage depend on the pHTo find out which fruits can light up the bulb longest.
  • 4. To observes the freshness of fruits affect on voltage and pHTo determine which fruits provide highest voltage depend on the pHTo find out which fruits can light up the bulb longest.
  • 5. introduction
  • 6. Batteries generate electricity by transformingchemical energy into electrical energy through achemical reaction between two different electrodesand one electrolyte (Giancoli, 2009). In our project we had replace batteries withdifferent type of fruits and study about their voltagereading, pH meter reading and its freshness. Fruitshave high of resistance and its not enough to light upLED.
  • 7. Type of fruits

  • 27. conclusion
  • 28. Is that the freshness of fruits affect the voltage and pH?
  • 29. Is that the freshness of fruits affect the voltage and pH?
  • 30. Is that the freshness of fruits affect the voltage and pH? Voltage will change either becomehigher or lower depend on the changes of citric acid in fruits (pH)
  • 31. Is that the freshness of fruits affect the voltage and pH?pH will change either become more acidic or less depend on the decomposition process
  • 32. Which fruits provide highest voltage depend on pH?
  • 33. Which fruits provide highest voltage depend on pH?
  • 34. Which fruits provide highest voltage depend on pH?Theory state:The more acidic will provide more voltage
  • 35. Which fruits provide highest voltage depend on pH?
  • 36. Which fruits provide highest voltage depend on pH?
  • 37. Objective failed
  • 38. improvement
  • 39. * Increase the quantity of fruits in the series of connection *Replace LED with clock and calculator*Increase contact area between fruits and zinc and copper
