Question 2: The relationship R = V/I tells us that the resistance of a conductor is directly proportional to the potential difference applied to it. What do you think on this proportion?
|Ohm’s law is one of the basic laws of current electricity. The law shows the ratio of the applied voltage of a conductor to the current flowing in it is constant. The constant depends upon the nature of the conductor, its dimensions and state of temperature. This is called resistance of the conductor.||Please note that some conductors do not follow Ohm’s law. Such conductors are called non-ohmic conductors. In such conductors, the ratio between V and I is not constant; it either increases or decreases with increasing the voltage.
See Ohm’s in detail.
