Most resistors youll see range between 1 ohm and 1 megaohm (1.0 M) they often have 5 tolerance but you can buy 1 or even 0.1 accuracy resistors. The bigger the resistance value (in ohms ) the more it fights. The fourth band gives resistance tolerance.Its colour is either silver or gold.Silver band indicates a tolerance of ± 10 % ,a gold band shows a tolerance of ±5 %.If there is no fourth band ,tolerance is understand to be ± 20%.By tolerance ,means the posible variation from the marked value.For example ,a 1000 Ω resistor with a tolerance of ± 10 % will have an actual resistance anywhere between 900 Ω and 1100 Ω.Ĭertain precision resistors with tolerance of 2 %, 1 %, or less are generally color coded with five bands as shown in figure given below:īegin at the band closest to one end.The first band is the first digit of the resistance value,the second band is the second digit,the third band is the third digit,the fourth band is multiplier ( number of zeroes after the third digit),and the fifth indicates the percent tolerance. Resistance is just what it sounds like, its the characteristic that makes a component fight current flow.The third band is decimal multiplier i.e,it gives the number of zeroes after the first two digits.Search only database of 7.4 mil and more summaries. Can be used as content for research and analysis. The second band gives the second digit. Collected from the entire web and summarized to include only the most important parts of it.The first band indicates the first digit in the numerical value of the resistance.The 5 band resistor colour bands are interpreted as follows:
