This section describes the fabrication of the cathode cable and integration of the cable into the custom-built CE system. We recommend that you look at the referenced pictures prior to performing any fabrication in order to avoid wasting materials.
- Using wire cutters, cut a length (~36 inches) of 22-gauge electrical wire into two equal pieces. Strip approximately ½” of the sheath from all four ends. Solder a 1kΩ resistor to the two cables, connecting them. Solder a platinum electrode to one of the ends of the cable.
- The ground cable should be connected to the ground on the power supply, which in turn is connected to the earth ground.
Power Supply Grounding Post
- The platinum electrode is inserted into the cathode reservoir vial.
- Integrate the voltmeter by using alligator clips to detect the voltage (or current) across the resistor.
