V - Potential difference (voltage) between ends of conductor (volts)


I - current

Believe  or not, Georg

Ohm was actually a high

school physics teacher!






Cross Multiply:  V = IR



V directly related to I 









Since ....


R = V/I


Slope of V, I plot = ???




Slope =

R = V/I

Slope = Resistance
