Studentswill also be introduced to the resistor color code andrefresh their graphing s Law states that the current,I, that flows in acircuit is directly proportional to the voltage,V, acrossthe circuit and inversely proportional to the resistance,R, of the circuit:I=VR( )In this Experiment , the current flowing through a resis-tor will be measured as the voltage across the resistoris varied. From the graph of this data, the resistance isdetermined for Ohmic resistors (Ri,i= 1, 2, 3).
