Question

Draw a graph between length and resistance of conductor

Answer 1

Answer:

R is directly proportional to l

then the graph will be a st. line passing through origin.

Answer 2

The graph will be a straight line

Step-by-step explanation:

Resistance is directly proportional to length of the wire and resistivity of the material.

Resistance is inversely proportional to cross sectional area.

So,

                   $R = \rho \frac{L}{A}$

Where,

                $R$= resistance

                $L$ = length of the wire

               $A$ = cross-sectional area
