Answer the following questions: (a) A steady current flows in a metallic conductor of non-uniform cross-section. Which of these quantities is constant along the conductor: current, current density electric field, drift speed ? (b) Is Ohm's law universally applicable for all cnducting elements ? If not, give examples of elements which do not obey Ohm's law. (c ) A low voltage suply from which one needs high currents must have very low internal resistance.Why (d) A high tension (HT) supply of say, 6kV must have a very large internal resistance, Why ?
