anodes, plural;
  1. The positively charged electrode by which the electrons leave a device

  2. The negatively charged electrode of a device supplying current such as a primary cell

  1. a positively charged electrode by which electrons leave an electrical device
  2. the negatively charged terminal of a voltaic cell or storage battery that supplies current
  3. An anode is an electrode through which electric current flows into a polarized electrical device. Mnemonic: ACID (Anode Current Into Device).
  4. (Anodes) Tin bars that are put in the plater cells and are important to the plating process in the Tin Mill.
  5. (anodes) Zinc buttons fastened near underwater metal fittings to protect from electrolysis corrosion.
  6. (anodes) metallic plates which, when attached to the hull of a vessel, decompose because of electrolysis, thereby reducing deterioration of hull plate. back
  7. The positive electrode in an electrochemical cell (battery). Also, the earth or ground in a cathodic protection system. Also, the positive terminal of a diode.
  8. The negative electrode of a battery (or other device).
  9. The positive electrode of an X-ray tube. In an X-ray tube, the anode carries the target.
  10. The "positive" terminal of a diode.
  11. The positive pole of an electrolytic system; the metal which goes into solution in a galvanic cell. Anodes of metals such as magnesium or zinc are sometimes installed in water heaters or other tanks to deliberately establish galvanic cells to control corrosion of the tank through the sacrifice ...
  12. One of two electrodes in a fuel cell or battery. In a fuel cell it is where the fuel reacts or "oxidizes", and releases electrons.
  13. The positive plate of a valve, the point where, or the path by which, a current enters the device.  Anode is also used for the positive end of many other things such as batteries, diodes and other electrically active items.
  14. Negative electrode of every electrochemical current source while being discharged.
  15. A source of positive charge or ions, and an attractor of free electrons.
  16. An electron collector. Means up the path from a negative to a positive voltage. An anode has a more positive voltage relative to a cathode.
  17. the electrode in an electrochemical cell at which oxidation occurs.
  18. The fundamental positively-charged electrode (negative pole) in a radio valve or radio tube; opposite to cathode. Sometimes referred to as a ‘plate’, especially in a diode.
  19. The material in a corrosive attack that becomes corroded. (top)
  20. The electrode by which current enters a mercury arc or solid-state valve (thyristor) in the conversion from alternating current to direct current. Current flow is from anode to cathode.
  21. An electrolyte carrying a positive charge
  22. The collector of electrons in an electrical circuit. Anodes have positive polarity with respect the cathodes.
  23. (Opposite of cathode) the electrode at which oxidation or corrosion occurs.
  24. The term in electroplating for the positive pole in the plating bath. A piece of metal (also called an anode) is attached to the anode. Metal from this anode is electro-deposited onto the item being plated (cathode).
  25. The positive pole or electrode of an electrolytic cell, vacuum tube, etc. (see also sacrificial anode).
