Abstract
PURPOSE: To determine the resistance of the conductive film by measuring the impedance between a pair of electrodes provided on the one surface of a dielectric through a capacitance combination of the electrodes and the film provided on the other surface thereof with the application of a high frequency signal between the electrodes.
CONSTITUTION: A pair of electrodes 11 and 12 arranged in a loop is provided outside a glass tube 2 as a dielectric and a high frequency signal from a high frequency signal source 13 is applied between the electrodes 11 and 12 to effect a capacitance combination of the conductive film 3 separately with the electrodes 11 and 12. The current i flowing between both the electrodes 11 and 12 is determined with an ammeter 14 to measure the impedance Z. The resistance R of the conductive film 3 attains the level as given by R≈v/i (where, v is the voltage of the power source 13) by increaing the area S of the electrodes 11 and 12, for example, with a larger width a. Thus, the resistance R can be estimated from the impedance Z.
