Definitions
from The American Heritage® Dictionary of the English Language, 5th Edition.
- noun A solid electric conductor through which an electric current enters or leaves an electrolytic cell or other medium.
- noun A collector or emitter of electric charge or of electric-charge carriers, as in a semiconducting device.
from The Century Dictionary.
- noun A pole of the current from an electric battery or machine which is in use in effecting electrolysis: applied generally to the two ends of an open electric circuit. The positive pole is termed the anode, and the negative pole the cathode.
