What's the difference between chemical and voltaic?

Chemical


Definition:

  • (a.) Pertaining to chemistry; characterized or produced by the forces and operations of chemistry; employed in the processes of chemistry; as, chemical changes; chemical combinations.
  • (n.) A substance used for producing a chemical effect; a reagent.

Voltaic


Definition:
