The values of current (

$I$ ) flowing through a resistor for various potential differences (

$V$ ) across the resistor are given below. What is the value of resistor?

I (ampere)	0.5	1.0	2.0	3.0	4.0
V (volt)	1.6	3.4	6.7	10.2	13.2

[Hint: Plot

$V-I$ a graph and take slope.]

From the given table,

$V-I$ graph is plotted.

V-I graph

Calculation of resistor value:

Consider taking the slope between the current values

$1.0$ and

$2.0$ .

$\begin{array}{l} Resistance = \frac{i_{i} - i_{i}}{i_{i} - i_{i}} \\ = \frac{i - i}{i - i} \\ = i Ω \end{array}$
