Electric Current Current- flow of electrons through a wire or any conductor. Potential difference (voltage)the difference in potential between two different places. Resistance- the tendency for a material to oppose the flow of electrons, changing electrical energy into thermal energy & light. Ohm’s Law- states that potential difference equals current times the resistance. -All conductors have some resistance. Ohm’s Law equation Variable Voltage (V) Current (I) Resistance (R) Ending Units volts amps ohms or Ω V=IxR I=V/R R=V/I . . V . . I x R
