The following measurements of current and potential difference were made on a resistor constructed of nichrome wire, where Vab is the potential difference across the wire and I is the current through it:
I(A) 0.50 1.00 2.00 4.00
Vab(V) 1.94 3.88 7.76 15.52
(a) Graph Vab as a function of I.(b) Does Nichrome obey Ohm's law? How can you tell?(c) What is the resistance of the resistor in ohms?
