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
