The figure below is current-versus-potential-difference graph for a material, in which each interval along the horizontal and vertical axes are 20 V and 1 A, respectively. What is the material\'s resistance? in .

Solution

The slope of the curve indicates the resistance.

the resistance is defined as follows:

R = V/I = 20 V/ 1 A = 20
