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.
Diode is a two terminal device (di-means two). Simply put, it acts as a one-way valve for electrons. Conventional current can flow from the anode to the cathode, but not in the other direction.If an intrinsic semiconductor is doped with a pentavalent or trivalent impurities you get a diode. Selenium diodes work much like any other diode. They allow current to flow in a forward direction and block current from flowing in the opposite direction. They have a h â¦ igher forward bias voltage then silicon and as such generate much more heat then a comparable silicon diode.
