اسلاید 1: ElectricityApril 23, 2007
اسلاید 2: Applications of Electrostatics
اسلاید 3: Electric ChargeMeasured in COULOMBSSix million trillion electrons is about - 1 C. Six million trillion protons is about + 1 C.
اسلاید 4: Electric Potential Energy
اسلاید 5: Electric Potential EnergyThis spring has more SPE when it is compressed
اسلاید 6: Electric Potential EnergyThis spring has more SPE when it is compressedLikewise, these charges will have more potential energy when they are pushed closer
اسلاید 7: Electric Potential EnergyPE equals the amount of work done to move a charge from one place to another.
اسلاید 8:
اسلاید 9: Electric Potential EnergyWhich will have the larger electric potential energy?
اسلاید 10: Electric Potential EnergyA – because it requires work to move it away from the negative charge.
اسلاید 11: Electric Potential (volts)EP = work/charge
اسلاید 12: Electric Potential (volts)Example: 1000 joules of work is done to move the charge q from far away to the place indicated. If q = 10 C, what is the electric potential at the new location?
اسلاید 13: Electric Potential (volts)Example: 1000 joules of work is done to move the charge q from far away to the place indicated. If q = 10 C, what is the electric potential at the new location? Voltage = work/chargeV = 1000 J/10C = 100 Volts
اسلاید 14: Electric Potential (volts)What if the charge in the previous problem were now 100 C instead of 10? What would happen to the EP?
اسلاید 15: Electric Potential (volts)What if the charge in the previous problem were now 100 C instead of 10? What would happen to the EP?IT WOULD BE THE SAME!!!Work would also increase
اسلاید 16: Electric Potential (volts)Electric potential is associated with LOCATION, not CHARGE
اسلاید 17: Electric Potential vs Potential EnergyWhich charge has more electric potential?Which has more potential energy?
اسلاید 18: Is 5000 Volts Dangerous?
اسلاید 19: Is 5000 Volts Dangerous?NOPE!When 1 million electrons are added to a neutral balloon, it has an electric potential of 5000 volts
اسلاید 20: Potential Difference (voltage)Difference in electric potential between two points.
اسلاید 21: Potential Difference (voltage)Difference in electric potential between two points.Potential difference between A and B is 0AB
اسلاید 22: Potential Difference (voltage)Difference in electric potential between two points.Now there is a potential differenceAB
اسلاید 23: Potential DifferenceBatteries provide potential difference between one end of the circuit and the other
اسلاید 24: Potential DifferenceBatteries provide potential difference between one end of the circuit and the otherCharges flow from high to low electric potential
اسلاید 25: Potential Difference (voltage)Why aren’t birds on power lines shocked?
اسلاید 26: Potential Difference (voltage)Why aren’t birds on power lines shocked?The Potential Difference between their feet is zero! (0 voltage)
اسلاید 27: Current (I)Net flow of electro
