Question

How to find resistance from V-I graph? With example. ​

Answer 1

Answer:

If the graph is sufficiently linear, calculating slope at two known points in this linear region can give you resistance. But if your graph isn’t linear, then you have to calculate instantaneous resistance as it clearly varies with current.

To measure instantaneous resistance at say (v,i) on the V-I graph, first draw a tangent to the curve at that particular point. Now calculate the slope of that tangent which will be instantaneous resistance at (v,i).
