Ohm's Law

1) R = V/I (at constant T)

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

I - current

(amperes)

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
