Solution

The graph between V & I  is a straight line.

So we can conclude that  Current flowing through the wire is directly proportional to the potential difference V across it.
The resistance of the wire can be calculated as 

`"R" = "v"/1 = 0.4/0.1 = 4Ω`

We can also conclude that nichrome wire has a constant value of the resistance as 4 Ω4 Ω.

nichrome wire follows ohm's law thus it behaves as an ohmic conductor.

The circuit diagram corresponding to the above graph is as shown below.
