  • The values of current (I) flowing through a given resistor of resistance (R), for the corresponding values of potential difference (V) across the resistor are as given below :

The values of current (I) flowing through a given resistor of resistance (R), for the corresponding values of potential difference (V) across the resistor are as given below :

 V(volts) 0.5 1.0 1.5 2.0 2.5 3.0 4.0 5.0
 I(amperes)  0.1  0.2  0.3  0.4  0.5  0.6  0.8  1.0 

Plot a graph between current (I) and potential difference (V) and determine the resistance (R) of the resistor.
