Presentation Transcript

  1. Ch.22 Current Electricity

  2. Current I=DQ/Dt Ampere-A • Rate of flow of charged particles at a point • Higher potential to lower • Positive to Negative=Conventional Current • Potential Difference =0 0-Current • Photovoltaic or Galvanic Dry Cell-Source of Chemical Energy • AC/DC • Diode----------------

  3. CONVENTION CURRENT VS. ELECTRON FLOW DRIFT VELOCTIY

  4. Power P=IV Watts-W • Rate at which energy is transferred

  5. Resistance R=V/I Ohms-Ω • Ohm’s Law-Current is directly proportionate to the resistance-Most Conductors Obey • Amount of current flowing • Ammeter
