Question

Draw a I–V graph for a linear resistor. What does its slope represent? 

Answer in Brief
Graph

Solution

One draws an I-V graph of a linear resistor. The slope represents the conductor's resistance, R.

Slope `("V"_"A" - "V"_"B")/("I"_"C" -"I"_"D")`

`(Δ "V")/(Δ "I") = "R"`

Graph for V vs I or slope

`(Δ "I")/(Δ "V") = 1/("Resistance of the conductor")`
