Resistor

Basically, all the materials have resistif but some materials such as copper, silver, gold and metal materials in general have a very small resistansi. The material is to dispatch electric current well, so named conductor. Reverse of conductive material, such as the material of rubber, glass, carbon resistansi have a greater flow of electrons and is called as the insulator. How conduction principle, described in the article about the semiconductor.

Resistor is the basic electronic components used to limit the amount of cash that flows in a series. In accordance with his name and resistif resistor are generally made of carbon materials. Ohms of the law known, resistansi inverted proportionate to the number of current that flows through. Resistansi of a unit called Ohm resistor or symbol is represented with W (Omega).

Resistor type that is common tubular copper with two feet on the left and right. In the body there is a circle shape bracelet color code to make it easier to identify the large size of the measure without resistansi with Ohmmeter. Color code is the standard issued by the manufacturer EIA (Electronic Industries Association) as shown in the table below. Time author entry registration study electrical engineering, there was a test that must be fulfilled that is required is not color-blind.
