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.
