b. The values of potential difference V applied across a resistor and the correponding values of current I flowing in the resistor are given below:

Potential difference, V (in volts)	:	2.5	5.0	10.0	15.0	20.0	25.0
Current, I (in amperes)	:	0.1	0.2	0.4	0.6	0.8	1.0

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

c. Name the law which is illustrated by the above V-I graph.

From the graph,

Resistance (R) = `V/I`

R = `5/0.2`

R = 25 Ω

c. Ohm’s law
