WebOhm's law states that the current through a conductor is proportional to the voltage across the conductor. This is true for many materials (including metals) provided the temperature (and other physical factors) remain … WebOhm ’ s law is an experimental law that is only fulfilled by some materials called ohmic materials. However, in general, resistance is a measure of a substance ’ s opposition to the flow of a current. This relationship can be as complex as we desire and depends on many variables, such as the specific material, temperature, etc.
