  2. Negative resistance - Wikipedia

    en.wikipedia.org/wiki/Negative_resistance

    Fluorescent lamp, a device with negative differential resistance. [1] In operation, an increase in current through the fluorescent tube causes a drop in voltage across it. If the tube were connected directly to the power line, the falling tube voltage would cause more and more current to flow, causing it to arc flash and destroy itself.

    A breach of the wall would have obliterated only a couple of small towns and a sparsely settled agricultural area in the relatively narrow 120 km Mitta Mitta valley below the dam, but more significantly, would have resulted in the over-topping and probable failure of the earthen walls of the 40m high 3,038GL Lake Hume, 200 km downstream on the ...

    T12 fluorescent tubes. The first two are rapid start, (for "tombstone" and socket holders respectively) while the third is an instant-start lamp. The instant-start has a characteristic, rounded, single pin, for plugging into the spring-loaded socket holders. Instant start fluorescent tubes were invented in 1944. Instant start simply uses a high ...

    The Pick plan introduced three different projects to be carried out by the Army Corps of Engineers. The first undertaking involved the construction of 1,500 miles of levees from Sioux City to the Mississippi River to protect from Missouri River flooding. The second proposal called for the construction of eighteen dams on Missouri's tributaries ...

  9. Cold cathode - Wikipedia

    en.wikipedia.org/wiki/Cold_cathode

    Some types contain a source of beta radiation to start ionization of the gas that fills the tube. [5] In some tubes, glow discharge around the cathode is usually minimized; instead there is a so-called positive column, filling the tube. [6] [7] [note 2] Examples are the neon lamp and nixie tubes. Nixie tubes too are cold-cathode neon displays ...
