Anode to what occurs in an electrolytic cell, no anions flow to the anode, the internal current being entirely accounted for by the cations flowing away from it (cf drawing). In the United States, many battery manufacturers regard the positive electrode as the anode, particularly in their technical literature. Though technically incorrect, it does resolve the problem of which electrode is the anode in a secondary (or rechargeable) cell. Using the traditional definition, the anode switches ends between charge and discharge cycles. In electronic vacuum devices such as a cathode ray tube, the anode is the positively charged electron collector. In
Electrode array resistance, particularly the contact resistance between the probe and the surface, which can be high. Assuming the material is homogenous, the resistivity is given by: Electrode arrays are widely used to measure resistivity in geophysics applications. It is also used in the semiconductor industry to measure the bulk resistivity of silicon wafers, which in turn can be taken as a measure of the doping that has been applied to the wafer, before further manufacturing processes are undertaken. Electrode array An electrode array is a configuration of electrodes used for measuring either an electric current or voltage. Some electrode arrays can
