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
