Read MoreHigh frequency plasma circuit (Electronic Ion Pump) This circuit utilizes a flyback transformer that has wire windings added to its ferrite core. The high-voltage, high frequency is the result of the transformer being driven into resonance at 20 to 170Khz. The flyback transformer supplies high-voltage, high frequency. Its output is in harmony with the Sea…
Read MoreA 120 watt carbon filament lamp and a 100 watt gas-filled tungsten filament lamp are about the same in size. As you have probably noticed, the 100 watt tungsten lamp not only emits more light, but it gets hotter. It appears to give out more heat, although using less power. Can you explain this? A…
