Draw a I–V graph for a linear resistor. What does its slope represent?
Advertisements
उत्तर
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")`
