2. Electrofishing - Wikipedia

   en.wikipedia.org/wiki/Electrofishing

   Electrofishing relies on two electrodes which deliver direct current at high-voltage from the anode to the cathode through the water. [2] When a fish encounters a large enough potential gradient on this path, it becomes affected by the electricity. Usually pulsed direct current (DC) is applied, which causes galvanotaxis in the fish ...

3. Standard electrode potential (data page) - Wikipedia

   en.wikipedia.org/wiki/Standard_electrode...

   The data below tabulates standard electrode potentials (E°), in volts relative to the standard hydrogen electrode (SHE), at: Temperature 298.15 K (25.00 °C; 77.00 °F); Effective concentration (activity) 1 mol/L for each aqueous or amalgamated (mercury-alloyed) species; Unit activity for each solvent and pure solid or liquid species; and

4. Electric pulse fishing - Wikipedia

   en.wikipedia.org/wiki/Electric_pulse_fishing

   The pulse trawl: electrodes in the tow direction of the gear cause an electric field above the seabed, which stimulate the flatfish so they come up toward the net Electric pulse fishing is a fishing technique sometimes used in trawl fisheries which produces a limited electric field above the seabed to catch fish.

5. Line focus principle - Wikipedia

   en.wikipedia.org/wiki/Line_Focus_Principle

   The cathode is negatively charged and consists of a focusing cup made of nickel and two filaments made of tungsten. The filament is a coil of tungsten of a specified size (usual large and small). When current passes through the wire, heat is produced and causes the filament to release or burn off electrons. This is known as thermionic emission ...

6. Copper–tungsten - Wikipedia

   en.wikipedia.org/wiki/Copper–tungsten

   Electrical resistivity increases with an increase in the percentage of tungsten present in the composite, ranging from 3.16 at 55% tungsten to 6.1 when the composite contains 90% tungsten. An increase in tungsten leads to an increase in ultimate tensile strength up until the alloy reaches 80% tungsten and 20% copper with an ultimate tensile ...

7. Tungsten - Wikipedia

   en.wikipedia.org/wiki/Tungsten

   Tungsten electrode used in a gas tungsten arc welding torch Tungsten filament is used in incandescent lightbulbs, where it is heated until it glows Because of its conductive properties and relative chemical inertness, tungsten is also used in electrodes , and in the emitter tips in electron-beam instruments that use field emission guns , such ...
