Study the $V - I$ graph for a resistor as shown in the figure and prepare a table showing the values of $I$ (in amperes) corresponding to four different values of $V$ (in volts). Find the value of current $I$ (amperes) for $V=10$ volts. How can we determine the resistance of the resistor from this graph?

(N/A) Based on the provided $V-I$ graph,we can observe the relationship between voltage $(V)$ and current $(I)$. The table below shows the values of $I$ corresponding to four different values of $V$:
$V$ (volts) $2$ $4$ $6$ $8$
$I$ (amperes) $1$ $2$ $3$ $4$

From the graph,when $V = 10 \text{ volts}$,the corresponding value of current $I$ is $5 \text{ amperes}$.
To determine the resistance $(R)$ of the resistor,we use Ohm's Law,which states $R = \frac{V}{I}$. The resistance is equal to the reciprocal of the slope of the $I-V$ graph,or the slope of the $V-I$ graph itself. Using the values from the graph:
$R = \frac{V}{I} = \frac{10 \text{ V}}{5 \text{ A}} = 2 \ \Omega$.
