Tolerance refers to the range of variation between the true value of the resistor and its design specifications. If there is no silver or gold band, the band closest to one of the leads will be considered the first one. A gold band represents a tolerance of +/-5%, and a silver band represents a tolerance of +/-10%. Calculating Resistor Values. The Resistor Colour Code system is all well and good but we need to understand how to apply it in order to get the correct value of the resistor. The “left-hand” or the most significant coloured band is the band which is nearest to a connecting lead with the colour coded bands being read from left-to-right as follows: As an interesting side note, it is likely that the thirty pieces of silver paid to Judas were made in Tyre. It was the nearest city to Jerusalem that consistently made large quantities of coins from the metal. Those who place a higher value on things made of silver rather than on repentance are condemned in the Bible (Revelation 9:20). silver – .01. An example of a resistance value is: band 1 = orange = 3, band 2 = yellow = 4, band 3 = blue = 1M. value = 34*1M = 34 Mohm. Resistance Tolerance. The fourth band is the tolerance and represents the worst case variation one might expect from the nominal value. The color code for tolerance is as follows: brown - 1% . red - 2%
A resistor colored Blue-Brown-Green-Silver-Blue would be 6.15 Ω with a tolerance of +/- 0.25%. Preferred Values or E-series. To make mass manufacturing of The first 4 bands make up the resistance nominal value. silver – .01 The fourth band is the tolerance and represents the worst case variation one might 7 Oct 2019 The multiplier value means the actual resistance value of our the “silver” color band on the resistor that the tolerance of this resistor is “5%”. green, blue, silver bands represent 56 × 0.01 = 0.56 ohm . resistor with a tolerance of ±10% will have a value within 10% of 390 ohm , between 390 - 39 = 351
1 Sep 2015 Suffix or fourth letter or alphabet represents the tolerance value of the by '10' and if the multiplier band is silver, divide the value by '100'.
Silver was used as a method of exchange (in the form of bars and other shapes) as early as the 1900s B.C. during the life of Abraham (Genesis 13:1 - 2). It was used, especially among common people, as a means to buy and sell goods far more frequently than gold.
The color of the first band indicates the value of the first significant digit. The third color band represents a decimal multiplier by which the first two digits must be multiplied In this example, the color silver indicates a tolerance of 10 percent.
