Most of the film resistors of the type of metal layer has a nominal value of a typical power dissipation of 250mW sebasar up to a nominal value of 2W.<\/span> In the resistor wire windings are made by wrapping the resistance wire in an insulating material.<\/span> Resistance of materials commonly used is chromium-nickel (nichrome), the compounds of nickel (Eureka), and compounds of nickel and silver.<\/span> The process of making is done by pulling the wire by using a molding machine that has been resized and then plated in order to produce good-quality.<\/span><\/p>\n

Wire that has been formed, must have good uniformity, can be easily formed, corrosion resistant, and has a fairly high resistivity.<\/span> Malleable ability is one of the essential requirement, thus if the wire is wound, it will not easily cracked or broken.<\/span> Characteristics and patterns of failure of the resistor depends on the type of material used, method of manufacture, operation and environmental situation, as well as the resistance value.<\/span><\/p>\n

At the time of operation, each resistor must dissipate power.<\/span> At low temperature conditions can be dissipated around the large amount of power, but for lower power dissipation will result in a better level of stability with a lower error rate.<\/span> Because in general the resistor has a uniform shape and construction, the rise in temperature caused by power terdisipasikan be maximum in the middle of the resistor body.<\/span> This process is called the temperature of hot spots.<\/span>

Example of How to read resistors with 4 color code<\/strong><\/span>
\n Ribbon-1 = RED = 2 (Value digits to-1)<\/span>
\n Ribbon-2 = PURPLE = 7 (2nd digit value)<\/span>
\n Pita 3rd = YELLOW = 1K = 1000 (Factor Multiplier)<\/span>
\n Pita 4th = GOLD = 5% (Tolerance)<\/span><\/p>\n

Jawabannnya is 27 x 1000 = 27,000 \u00b1 5% \u00b1 5%<\/u><\/span>
\n R max = 27.000 + (5% x 27,000) = 28 350 \u03a9<\/span>
\n R min = 27,000 – (5% x 27,000) = 25,650 \u03a9<\/span><\/p>\n

Example of How to read a resistor with 5 color code<\/strong><\/span>
\n Ribbon-1 = BLUE = 6 (Score digits to-1)<\/span>
\n Ribbon-2 = RED = 2 (2nd digit value)<\/span>
\n Pita 3rd = BROWN = 1 (Rated digit 3rd)<\/span>
\n Pita 4th = BROWN = 10 (Factor Multiplier)<\/span>
\n Pita 5th = BROWN = 1% (Tolerance)<\/span><\/p>\n

The answer is: 621 x 10 \u00b1 1% = 6.210 \u00b1 1%<\/u><\/span>
\n R max = 7,540 + (1% x 7,540) = 7615.4 \u03a9<\/span>
\n R min = 7540 – (1% x 7,540) = 7464.6 \u03a9<\/span>
