Remark:
AWG:
An electronics industry acronym for American Wire Gauge. AWG is a measure of the thickness of copper, aluminum and other wiring in the U.S. and elsewhere. Copper cabling typically varies from 18 to 26 AWG. The higher the number, the thinner the wire. The thicker the wire, the less susceptible it is to interference. AWG is known as BS (Brown & Sharp wire gauge). The AWG gauging system is defined as a geometrical progression because of the drawing mechanism nature. The 36 AWG is defined as 5 mil diameter, and the 4/0 AWG is defined as 460 mil diameter. In general, thin wire cannot carry the same amount of electrical current the same distance that thicker wire can. 


MIL:
A measurement of length or width; also of volume and angle. One mil is 0.001 inches length or width; in England, I am told that the term "thou" is 0.001 inch. Used frequently in measuring very large wire sizes. The circular mil is a unit of area used especially when denoting the cross-sectional size of a wire or cable. It is the equivalent area of a circle whose diameter is 0.001 (10-3) inch, or approximately 0.7854 millionths of a square inch (or 2.5 x 10-7 times pi). In plane geometry, area always varies in direct proportion to the square of the linear dimension. Thus, if wire A is twice the diameter of wire B, then wire A has four times the cross-sectional area, in circular mils, of B. If wire C is 1/5 of the diameter of wire D, then C has 1/25 the cross-sectional area, in circular mils, of D. In this respect, the circular mil is like any other unit for measurement of area. Because the circular mil is, as its name implies, based on a circular unit of measure rather than a rectangular unit, conversions between circular mils and square units such as the meter squared (m2) or centimeter squared (cm2) can be awkward. To convert circular mils approximately to meters squared (m2), multiply by 5.066 x 10-10. Conversely, multiply by 1.974 x 109. To convert circular mils approximately to centimeters squared (cm2), multiply by 5.066 x 10-6. Conversely, multiply by 1.974 x 105.

As to volume, a metric unit of volume is equal to one thousandth of a liter. With respect to circular angular measurement, a mil (in military terms) is equal to 1/6400 of a complete revolution.


Satu pertanyaan dari saya: Kenapa di Indonesia banyak kejadian kebakaran yang disebabkan oleh hubungan singkat (short circuit) arus listrik? .... Jawabannya: Salah satunya karena Ilmu listrik ini tidak digunakan. Sehingga kekuatan kabel tidak diperhitungkan dengan beban listrik yang terpasang. Kualitas kabel juga sangat mempengaruhi, jadi jangan sembarang menggunakan kabel listrik asal merek, kabel buat speaker dipakai buat listrik.. hal ini banyak terjadi di lingkungan kita. So, Gunakan ilmunya, Insya Allah pasti aman.
