Question

33 According to Ohm's law the graph of potential
difference and current is
(A) Straight line passing through origin
(B) Curved
(C) Line having an intercept on X-axis
(D) Circular
​

Answer 1

Answer:

(a) Straight line passing through the origin

Explanation:

According to the Ohm's law, so long the temperature or other physical states of conductor do not change ,the resistance of the conductor remains constant whatever potential difference is applied between the ends of the conductor.

If a graph be drawn between the applied potential difference V and the current I that flow through the conductor then it will be a straight line Ohm's law is true for metallic conductors only.

Answer 2

a) straight line passing through origin
