The values of current I flowing in a given resistor for the corresponding values of potential difference V across the resistor are given below −

I (amperes )     0.5      1.0    2.0    3.0       4.0

V (volts)           1.6      3.4    6.7    10.2     13.2

Plot a graph between V and I and calculate the resistance of that resistor.  ( 3 MARKS )
