How is the current related to the potential gradient in conductor? If two terminal point on a conductor are held at a constant potential difference V, e.g., by connecting them to the electrodes of battery, then in equilibrium a steady current flows through the conductor. Let I be the current at either point, It is found that for many cases the current and potential difference are proportional, equation V=IR is Ohm’s law. The constant of proportionality R is called the resistance of the conductor. The SI unit of resistance is the ohm, 1/R is called the conductance, and its unit is Siemens. Ohm’s law holds to a very good approximation for many conductors. However, it is not a universal principle, and in sec.7.7 we will see an example where it doesn’t hold.
