V-i characteristics curve of ohm's law

Ohm's law states that where is the Voltage across a resitor,    a constant which represents the electrical resistance of the resistor in question, and   is the current flowing through the resistor. This law can be viewed as describing the relationship between the voltage and current for any resistor of resistance  

This law states that the voltage across a resistor is directly proportional to the current. This means that when the voltage across the resistor increases, the current flowing through that resistor will also increase. Likewise, when the voltage across the resistor decreases, the current flowing through the resistor will  also decrease. It is also worth noting that , when there is no voltage across the ends of the resistor, there will be no current flowing through the resistor.

Ohm's law can be represented in a graph with the voltage   is on the  -axis and the current   is on the  -axis.  The gradient of such a graph will be the resistance. A graph  of the   characteristics for a 2Ω resistor is attached with this solution.

it should be -8.6 cm hope this out

i. like it i'm gonna edit it tomorrow
