Q26 of 33 Page 1

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


Plot a graph between V and I and calculate the resistance of the resistor.

The graph is as below


We know V = IR


Slope of V versus I graph will give R


R =(V2 – V1)/(I2 – I1)


= (10.2 – 6.7)/(3.0 – 2.0)


R = 3.6 ohm
