3. Many modern electronic devices do not obey Ohm's law; that is, V # IR. They rely on a more complicated relationship between current I and potential difference V for their operation. Suppose you measured the current and potential difference for one of these devices and found the following results: I (A) V (V) 0.200 2.50 0.400 6.30 0.600 10.8 0.800 15.8 1.00 21.4 If it is known that the relationship between the current and potential difference obeys the general n law V = k (+)", plot a straight-line graph by hand on the graph paper provided below of the appropriate variables and use it to find values (with units) for k and n. Use I。 = 0.200 A. Please show each step of your calculations.
