  2. Weston cell - Wikipedia

    en.wikipedia.org/wiki/Weston_cell

    Drawing from Edward Weston's US Patent 494827 depicting the standard cell. Weston cell Standard cell, extracted from case. Made in USSR. The Weston cell or Weston standard cell is a wet-chemical cell that produces a highly stable voltage suitable as a laboratory standard for calibration of voltmeters.

  3. Cathodic protection - Wikipedia

    en.wikipedia.org/wiki/Cathodic_protection

    Polarization of the target structure is caused by the electron flow from the anode to the cathode, so the two metals must have a good electrically conductive contact. The driving force for the cathodic protection current is the difference in electrode potential between the anode and the cathode. [9]

  4. Silver oxide battery - Wikipedia

    en.wikipedia.org/wiki/Silver_oxide_battery

    A silver oxide battery (IEC code: S) is a primary cell using silver oxide as the cathode material and zinc for the anode. These cells maintain a nearly constant nominal voltage during discharge until fully depleted. [ 2 ]

  5. Electrochemical cell - Wikipedia

    en.wikipedia.org/wiki/Electrochemical_cell

    A secondary cell produces current by reversible chemical reactions (ex. lead-acid battery car battery) and is rechargeable. [citation needed] Lead-acid batteries are used in an automobile to start an engine and to operate the car's electrical accessories when the engine is not running. The alternator, once the car is running, recharges the battery.

  6. Galvanic anode - Wikipedia

    en.wikipedia.org/wiki/Galvanic_anode

    A galvanic anode, or sacrificial anode, is the main component of a galvanic cathodic protection system used to protect buried or submerged metal structures from corrosion. They are made from a metal alloy with a more "active" voltage (more negative reduction potential / more positive oxidation potential ) than the metal of the structure.

  7. Wiring diagram - Wikipedia

    en.wikipedia.org/wiki/Wiring_diagram

    An automotive wiring diagram, showing useful information such as crimp connection locations and wire colors. These details may not be so easily found on a more schematic drawing. A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the ...

  8. Magnesium battery - Wikipedia

    en.wikipedia.org/wiki/Magnesium_battery

    The magnesium–air battery is a primary cell, but has the potential to be 'refuelable' by replacement of the anode and electrolyte. Some primary magnesium batteries find use as land-based backup systems as well as undersea power sources, using seawater as the electrolyte. [5] The Mark 44 torpedo uses a water-activated magnesium battery.

  9. Control grid - Wikipedia

    en.wikipedia.org/wiki/Control_grid

    Schematic symbol used in circuit diagrams for a vacuum tube, showing control grid. The control grid is an electrode used in amplifying thermionic valves (vacuum tubes) such as the triode, tetrode and pentode, used to control the flow of electrons from the cathode to the anode (plate) electrode.
