Question

draw the V-I graph for metallic wire . what does its slope indicate

Answer 1

Hey there !

V - I Graph is a graph drawn between the Potential Difference and the Current of a given conductor in a circuit.

The slope of this graph gives us the Resistance of the conductor used in the circuit.

This is called as the Ohm's Law where if the Potential Difference and Current is divided with each other under a particular temperature and pressure, the Resistance or the ratio of V to I will not change.

Refer to the image for sample Graph.

Hope my answer helped !

Answer 2

Heya!
--------

-----------------------------------------------------------------------------------------------------

◾The graph between Potential Difference ( V ) and Current ( I ) is a straight line that passes though the Origin ( O )

◾The slope of the graph depicts that Current and Resistance are Inversely proportional to each other .

◾Due to the decreasing temperature , Resistance in a metallic wire increases due to more collisions between molecules .
