Usage Instructions
Depending on whether AC or DC output is required, position the brushes at either end or the center of the copper ring. When using as a power source, connect the external power supply to the terminals on the wooden base. During operation, press the wooden baseplate with one hand while steadily rotating the large wheel with the other to generate power output. Avoid excessive rotation speed to prevent overvoltage that could burn out the bulb. When connecting a demonstration ammeter, always incorporate a voltmeter in series; never connect the ammeter alone in series. If necessary, series-connect a sliding resistor as the load.
