The magnitude of the resistance of a resistor is read from the position of the most front ring ring towards tolerance.<\/span> Usually position tolerance ring is located at the corner of the resistor body or also with a width of more prominent, while the position of the first ring slightly inward.<\/span> Thus the user already knows how the tolerance of the resistor tersebut.Kalau we have been able to determine which of the first ring next is reading the resistance value.<\/span><\/p>\n

The amount of the ring in accordance with a general resistor tolerance.<\/span> Usually resistor with a tolerance of 5%, 10% or 20% had 3 rings (excluding ring tolerance).<\/span> But resistors with a tolerance of 1% or 2% (small tolerance) has 4 rings (not including tolerance ring).<\/span> The first ring and so on successively shows the great value of the unit, and the last ring is the multiplier factor.<\/span> For example, a resistor with a ring of yellow, violet, red and gold.<\/span><\/p>\n

Gold ring is a ring of tolerance.<\/span> Thus the order of the colored ring this resistor is, the first ring of yellow, violet and a second ring to the three red rings.<\/span> The fourth ring is gold colored tolerance ring.<\/span> From table 1.1 is unknown if the tolerance rings gold, meaning these resistors have a tolerance of 5%.<\/span> The resistance value calculated in accordance with the order of the color.<\/span><\/p>\n

The first is to determine the unit value of this resistor.<\/span> Because of this resistor resistor 5% (which usually has three rings in addition to the ring tolerance), then the value of the units is determined by the first ring and the second ring.<\/span> Still from table 1.1, known yellow ring and ring value = 4 violet value = 7. So the first ring and the second or yellow and violet sequence, the value of the unit is 47. Ring the third is a multiplier factor, and if the color of the red ring means the multiplier factor adalah100 ,<\/span><\/p>\n

So with this in mind the resistor value is the value of x multiplier unit or 47 x 100 = 4700 Ohm = 4,7K Ohm (on the electronic circuit board usually 4K7 Ohm) and the tolerance is + 5%.<\/span> The meaning of tolerance itself is limit the minimum and maximum resistance values \u200b\u200bwhich is owned by the resistor.<\/span> So the actual value of the resistor 4,7k Ohm + 5% is: 4700 x 5% = 235<\/span>
\n So,<\/span>
\n Rmaksimum = 4700 + 235 = 4935 Ohm<\/span>
\n Rminimum = 4700 – 235 = 4465 Ohm.<\/span><\/p>\n

If the above resistor is measured using an ohmmeter and its value is in the range of maximum and minimum values \u200b\u200b(4465 s \/ d 4935), the resistors were still meet the standards.<\/span> This tolerance value is given by the manufacturer of resistors to anticipate the material characteristics are not the same between one resistor with another resistor so that the electronics designers can estimate the tolerance factor in its design.<\/span><\/p>\n

The smaller the tolerance value, the better the quality the resistor.<\/span> So the market resistor having a 1% tolerance value (example: resistor metalfilm) is much more expensive than resistors have a tolerance of 5% (carbon resistor).<\/span> Other specifications that need to be considered in choosing a resistor on a draft in addition to a large resistance is his or her great-watt maximum power capable of being held by a resistor.<\/span> Because the resistor works in aliri electric current, there will be a power dissipation of heat for:<\/span>
\n<\/a><\/p>\n

The larger the physical size of a resistor, can demonstrate the greater the ability of the resistor power dissipation.<\/span> Generally in the market available sizes 1\/8, 1\/4, 1\/2, 1, 2, 5, 10 and 20 watts.<\/span> Resistors have maximum power dissipation 5, 10 and 20 watts are generally shaped beam extending rectangular white, but some are cylindrical and usually for the resistor size is the resistance value in the direct printing dibadannya not shaped rings of color, for example 100\u03a95W or 1K\u03a910W.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
