I-V graph for a linear resistor

Draw an I-V graph for a linear resistor. What does it's slope represent? Current Electricity, Concise Physics Solutions ICSE Class 10.

Slope of I-V graph — The slope of I-V graph is ΔIΔV\dfrac{ΔI}{ΔV} which is the reciprocal of resistance of the conductor i.e.,

Slope = ΔIΔV\dfrac{ΔI}{ΔV} = 1resistance of the conductor\dfrac{1}{\text{resistance of the conductor}}
