The spheres are 13 cm in diameter and made of nickel-plated ABS plastic. They are mounted on insulating rods that are made of clear polycarbonate (about 10 14 ohm) and attach to a support base. Each sphere contains a thumbscrew terminal on the lower half of the sphere for attaching a ground cable or a lead from a power supply. ä Note: When handling the conductive spheres, take care to keep each sphere and insulating rod free of dirt, grease, and fingerprints to minimize leakage of charge from the spheres. Operation with a Power Supply To use the conductive sphere with the PASCO ES-9049A Power Supply, connect one of the power supply output terminals (+30 V or + 100 V) to the thumbscrew terminal on the conductive sphere. If you are using the PASCO ES-9054B Electrometer to
