Hint The materials which conduct electricity due to the free electrons when an electric potential difference is applied across them are known as the conducting materials. Based on this property we have to answer this question.
Complete step by step answer:
We should know that conducting material obeys ohm’s law. Based on this fact we can classify the conducting or insulating devices.
Let us consider a solution when the resistivity of a material is independent of magnitude and direction of the applied electric field.
Now on the other hand it is already mentioned by us that a conducting device obeys ohm’s law when the resistance of the device is independent of the magnitude and the polarity of the applied potential difference.
So, we can say that a conducting material obeys ohm’s law when the resistivity of material is independent of its magnitude and direction of the applied electric field.
Hence, the correct answer is Option A.
Note We know that Ohm’s law states that the voltage across a resistor is directly proportional to the current which is flowing through the resistance. This law is used to establish a relationship between current, voltage and resistance.
