CH.22 CURRENT ELECTRICITY
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----------------
DRIFT VELOCTIY
CONVENTION CURRENT VS. ELECTRON FLOW
Power P=IV Watts-W
Rate at which energy is transferred
Resistance R=V/IOhms-Ω Ohm’s Law-Current is directly
proportionate to the resistance-Most Conductors Obey
Amount of current flowing Ammeter
