Question

Graph as shown in figure was plotted between V and I . Find the values of V and I corresponding to points A and C on the graph . Analyse these values and draw conclusion .

Answer 1

v = I * R
R = V / I
FROM GRAPH , V = y AND  I =x
-----> R = slope of the graph
             = y /x
              = 0.15 - 0.05 / 1.5 - 0. 5
              = 0.1 / 1
               = 0.1 ohm 

Answer 2

Answer:

0.1 ohm is the value of V and I corresponding to points A and C on the graph.

Explanation:

By Ohm's law V=IR, where V= voltage, I= current, R= Resistance.

Resistance means the ratio of voltage to current.For all or part of an electric circuit at a fixed temperature is generally constant.

So, V=IR

R=V/I

In the graph,we can see V= y and I= x and R is slope of the graph.

So, R= y/x =(0.15-0.05)/(1.5-0.5) = 0.1/1 = 0.1 ohm
