 barretter
 鐵氫鎮流電阻; 穩流燈

From: Webster's Revised Unabridged Dictionary (1913)

 bar·ret·ter n.
 1. Electronics a resistor inserted into a circuit to compensate for changes (such as those arising from temperature fluctuations); a thermal cymoscope.
 Syn: -- ballast resistor.
 Note: ☞  The original form consisted of an extremely fine platinum wire loop attached to terminals and inclosed in a small glass or silver bulb. It operates by increased resistance when subjected to the influence of an electric current. In a later variety, called the liquid barretter, wire is replace by a column of liquid in a very fine capillary tube.  A recent version has a resistor composed of an iron wire in a glass bulb containing hydrogen, with the temperature variation of resistance such that the current passing through it remains constant over a wide range of applied voltages.
