You all remember Ohm's law and the definition of electricalresistance as the ability of a circuit to resist the flow ofelectrical current. Although useful, Ohm's law applies to only onecircuit element and assumes it to be an ideal resistor. Real-worldcircuit elements are more complex and exhibit...more >>
