  1. Sources of Electrical Energy & Flow SNC1P

  2. COPY INTO NOTES

  3. Electricity : a form of ENERGY INTERACTION BETWEEN + and - charges Static Flow (BUILT UP CHARGES) (MOVING CHARGES) Cotton Shirt Wool Sock Plastic Wrap Plate Cloud Ground What are some things that FLOW?

  4. What are some things that FLOW? Flow (MOVING)

  5. We need a SOURCEof energy for FLOW to occur Source: Source: Source:

  6. Electricity : a form of ENERGY INTERACTION BETWEEN + and - charges Static Flow (BUILT UP CHARGES) (MOVING CHARGES) Protons or Electrons Electron Flow ? Insulator Conductor

  7. We need a SOURCEof energy for FLOW to occur Sources:

  8. Sources of Electrical Energy & Flow Date: Source: Device that supplies electrical energy Ex: Battery Outlet

  9. How Does a Battery Work ? + Positive Terminal CHEMICAL ENERGY Chemical Changes Paste ELECTRICAL ENERGY • - NegativeTerminal

  10. VIDEO

  11. How Does a Battery Work ? Due to a chemical reaction in the battery paste, the negative end builds up an excess of electrons. Electrons move from the negative terminal to the positive terminal. Chemical Energy  Electrical Energy

  12. Potential Difference 120 V 1.5 V

  13. Potential Difference: change in the energy of a • unit of charge after passing through a source or load • Also called VOLTAGE

  14. Potential Difference 120 V 1.5 V

  15. Potential Difference: Analogy 4.5V 3V vs. 1.5V 1.5V

  16. Potential Difference: Analogy Batteries ? • vs.

  17. Potential Difference: Analogy Potential Difference Electric Charge

  18. vs.

  19. A B C D E

  20. Potential difference (V) is measured in Volts (V). Voltmeter:the device that measures the potential difference between TWO POINTS in a circuit

  21. A constant flow of electrical energy can drive a • steady current (FLOW of charges).

  22. Electricity : a form of ENERGY INTERACTION BETWEEN + and - charges Static Flow (BUILT UP CHARGES) (MOVING CHARGES) Electron Part of the atom that flows ? Provides energy for the flow of electrons ? Source Battery Source that is typically 1.5 V ? Potential Difference Change in energy across 2 points ? Potential Difference Also called Voltage ? Voltmeter Measures Potential Difference ?
