Question

The graph of a conductor between the potential
difference (V) and current / is shown in figure given
alongside. Calculate the resistance of the conductor.​

Answer 1

Answer:

We know that

v=ir

so

r=v/I

as the slope gives us I/v (conductance) hence to obtain resistance we will find 1/slope

$slope = \frac{3}{30} = \frac{1}{3} \\ hence \: resistance \: = \frac{1}{ \frac{1}{3} } = 1 \times \frac{3}{1} = 3 \: ohm$
