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 plotted by using the given data is shown below:

The graph between V and I plotted by using the given data is shown below:


If we look at the graph, we find that when potential difference V is 8.5 volts, then the corresponding current value is 2.5 amperes. Now, Resistance,



Thus, the resistance of the resistor is 3.4 ohms.
