Presentation Transcript

  1. ELECTRICITY

  2. Circuits What are they? • Circuits are a path along which electricity moves Closed, series circuit

  3. Kinds of Circuits

  4. Kinds of Circuits

  5. Series Circuits

  6. Parallel Circuits

  7. Voltage Voltage is defined as the amount of work done or the energy required in moving a unit of positive charge (1 coulomb) from a lower potential to a higher potential. Voltage is also called potential difference (PD).

  8. Current • Current is the amount of electric charge (coulombs) flowing past a specific point in a conductor over an interval of one second.  1 ampere = 1 coulomb/second = 6.24 x 1018 electrons • Electron flow is from a lower potential (voltage) to a higher potential (voltage).

  9. Resistance Resistance • Charges passing through any conducting medium collide with the material at an extremely high rate and, thus, experience friction.

  10. Resistance • The rate at which energy is lost depends on the wire thickness (area), length and physical parameters like density and temperature as reflected through the resistively

  11. Ohm’s Law • There is a simple linear relationship between voltage, current and resistance. Georg Ohm

  12. Electricity • Know what it is • Know the different kinds • Know about the different kinds of circuits • Know about conductors and insulators

  13. ElectroBoard • Unfold and write the first matching column on the left hand side. • On the right hand side, write the second matching column. • Place a brad in the first hole on the left side. Locate the correct answer on the right side and place a brad in that hole. • Connect the brads with a strip of aluminum foil. • Tape the ENTIRE strip of foil down between each item! • 9. This creates a series circuit that you can use for review. All you need to test the item is a continuity tester or a series circuit setup.
