Question

the graph between V and I is always _according to ohm's law​

Answer 1

Answer:

Ohms law states that the current flowing through the cross section of a wire(I) is directly proportional to the voltage across it(V) provided the temperature does not change and it is equal to a constant which is called resistance.

Answer 2

Explanation:

Ohm's law:

   The graph between the potential difference V and the current I flowing through a metallic conductor is a straight line curve. In the operating range of values, the relation between the voltage V and the current I is linear.

    V = I R 

 R = resistance of the metallic conductor.

R is obtained by finding the slope of the graph.  

  R = (V2 - V1)/(I2- I1)
