bioelectricity
electric potentials and currents produced by or occurring within living organisms. Bioelectric potentials are generated by a variety of biological processes and generally range in strength from one to a few hundred millivolts. In the electric eel, however, currents of one ampere at 600 to 1,000 volts are generated. A brief treatment of bioelectricity follows. For full treatment, see electricity: Bioelectric effects
