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 (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 the resistor.

∴ Resistance, R = \(\frac{V}{I}\)
= \(\frac{15V}{4A}\) = 3.75Ω
