Measurements of low-impedance thin-film tunneling junctions at room temperature frequently yield inaccurate values for the tunneling resistance. In some cases the indicated resistance is negative. A theory is developed which shows that the finite resistance of the metal films can account for the observations. Results, given for the resistance of a tunneling junction as a function of temperature, show good agreement between theory and experiment.
