Fuse, electric
safety device used to protect an electric circuit against an excessive current. A fuse consists of a low-melting-point alloy strip enclosed in a suitable housing and connected in series with the circuit that it protects. Because of its electrical resistance, the alloy strip is heated by electric current; if the current exceeds the safe value for which the fuse was designed, the strip melts, opening the circuit and stopping the current.
Electric and magnetic units
units used to express the magnitudes of various quantities in electricity and magnetism. Three systems of such units, all based on the metric system, are commonly used. One of these, the mksa-practical system, is defined in terms of the units of the mks system and has the ampere of electric current as its basic unit. the units of this system-the volt, ohm, watt, and farad-are those commonly used by scientists and engineers to make practical measurements. the two other systems, now being gradually abandoned, are both based on the cgs system. Electrostatic units (cgs-esu) are defined in a way that simplifies the description of interactions between static electric charges; there are no corresponding magnetic units in this system. Electromagnetic units (cgs-emu), on the other hand, are defined especially for the description of phenomena associated with moving electric charges, i.e., electric currents and magnetic poles.
Electric fish
Any of many unrelated species of fish that have electric organs, usually made of modified muscle tissue, that are capable of producing from 450 to 600 volts of electricity. This electricity is used to detect and paralyze prey, repel enemies, navigate, and possibly communicate. Important electric fish include the electric eel, the electric catfish, and the electric ray, or torpedo.
