The value of current, `I`, flowing in a given resistor for the corresponding values of potential difference, `V`, across the resistor are given below :
`{:(I("ampere"),0.5,1.0,2.0,3.0,4.0),(V("volt"),1.6,3.4,6.7,10.2,13.2):}`
Polt a graph between V and I and calculate the resistance of the resistor.
