First Play will be Thursday, August 3, at 10:00 a.m., featuring a three-mile long human chain of area youngsters stretching from the Frank T. Bow Building in downtown Canton (201 2nd Street S.W.) where the NFL was founded in 1920, to the Pro Football Hall of Fame.
diode (dÄ«'Åd') An electrical device with two active terminals, an anode and a cathode, through which current passes more easily in one direction (from anode to cathode) than in the reverse direction. Diodes have many uses, including conversion of AC power to DC power, and the decoding of audio-frequency signals from radio signals.
First, what is a diode? A diode is a semiconducting device, that allows current to flow in one direction but not the other. A semiconductor is a kind of material, in this case silicon or germanium, whose electrical properties lie between those of conductors (metals) and insulators (glass, rubber).hen the voltage across the diode is positive, a lot of current can flow once the voltage becomes large enough. When the voltage across the diode is negative, virtually no current flows. 1  N-type: With N-type doping, phosphorus or arsenic is added, in parts per billion, to the silicon in small quantities.
