  1. Electricity

  2. Electricity Electricity is due to the flow of electrons Electricity flows through a path called a circuit

  3. Electricity Types of Circuits Series Circuits Parallel Circuits

  4. Electricity Series Circuits – have only one path for electricity to flow

  5. Electricity If any part of a series circuit is broken, the circuit fails. If either light is unscrewed both lights will turn off

  6. Electricity

  7. Electricity Parallel Circuit – have multiple paths for the electricity to flow

  8. Electricity The branches (paths) of a parallel circuit are independent. If either light is unscrewed, the other will remain on.

  9. Electricity

  10. Electricity Circuit diagrams and electrical symbols

  13. Electricity Three Quantities of a Circuit: Voltage Current Resistance

  14. Electricity Voltage pushes electricity through a circuit

  15. Electricity Voltage is related to potential energy, it flows from high energy to low energy, just like water

  16. Electricity

  17. Electricity

  18. Electricity Current -is the flow of charge -is measured in Amps -current is moving electrons -increasing current causes more electricity to move through a device

  19. Electricity Current is what carries energy Electric current flows from high electrical potential energy to low.

  20. Electricity Current -one Amp is a flow of 1 coulomb of charge per second

  21. Electricity Electric current flows in a circuit from the positive end of a battery and returns toward the negative end.

  22. Electricity Current must pass through the meter when it is being measured.

  23. Electricity Voltage -is measured in Volts -is electric potential, (how much work a battery can do) -to increase voltage, use a stronger battery or add batteries

  24. Electricity Voltage is measured from one point to another. The negative terminal (-) of a battery the point of reference; here the voltage is zero volts, (0 volts)

  25. Electricity

  26. Electricity Every point in a circuit connected to the same wire is the same voltage

  27. Electricity Voltage is linked to energy: 1 Volt of Voltage = 1 joule of energy per coulomb of charge

  28. Electricity Current is what actually flows and does work. A difference in voltage provides the energy that causes current to flow.

  29. Electricity A voltage difference of 1 volt means 1 amp of current does 1 joule of work in 1 second.

  30. Electricity The voltage in your home electrical system is 120 volts, which means each amp of current carries 120 watts of power.

  31. Electricity

  32. Electricity Resistance - is the measure of how strongly a wire or other object resists current flowing through it.

  33. Electricity Resistance -slows down current -adding devices in a circuit increases resistance -Resistance is measured in Ohms

  34. Electricity Resistance and Current -if resistance is high, not much current flows -if resistance is low, a lot of current flows

  35. Electricity Resistance and Current

  36. Electricity Resistance and Current Every device that uses electrical energy adds resistance to a circuit.

  37. Electricity Resistance and Current

  38. Electricity Resistance -One volt causes a current of 1 amp to flow through a resistance of 1 Ohm

  39. Electricity A multimeter can be used to measure resistance of a device that has been completely removed from the circuit.
