Problem

A device is tested, and the following data are recorded: (0.0 V, 0.00 A)(0.0\,\text{V},\,0.00\,\text{A}), (4.0 V, 0.80 A)(4.0\,\text{V},\,0.80\,\text{A}), and (8.0 V, 1.20 A)(8.0\,\text{V},\,1.20\,\text{A}). Determine the average resistance in the interval 0–4 V and in the interval 4–8 V, and state whether the device exhibits ohmic behaviour.
