Five Resistance Band Color Code What Does The Last Band Of White Color Represent
Five Resistance Band Color Code What Does The Last Band Of White Color Represent In electronic repair, most of the time I arrived at five band resistor color code. The objective of using the five color band resistor in a circuit is to provide a more accurate comparison of the four bands of color. For example, to obtain the value of resistance 22.6kohm with four bands of color, will not be able to find it. The more you can get is 22k (red, red, orange and gold). If the five bands of color, you will be able to calculate (red, red, blue, red, brown), the last of which is brown represent 1% tolerance. May you go to Google search engine strength of color and the type of code, the color coding of resistance, resistance color code calculator, or resistor color code chart to know more about how to calculate band five values of resistance. If you open an analog multimeter, you understand what I mean. Most of the resistance within the circuit multimeter are using five color bands. Why? Since the reading is obtained every time you measure current, voltage or ohm, the panel show the nearest value. For example, if a battery is measured from the tip of 9Volt in May from 8.9v, 9v, or 9.1 volts. If the multimeter was designed using four bands of color that the resistance on the outcome, it's May 8.5V, 9.5vo even 10 volts. In other words, the use of five color bands of resistance to a circuit of production more accurately and the desire that this result is that engineers want. There are a lot of interesting five color strength which is unique. In fact, I have already seen a number of them. I reveal the single calculation for a period of five hours on this type of resistance to color. The colors are orange, orange, red, gold, white. In reality, this is a band of four colors of resistance. Ignore the color white and the calculation using the formula of four bands of color. As for why the resistance from manufacturers to add this' extra 'white band I really do not know. However, the forum someone said it was for the military. If you know the answer I would like to send me an e-mail so I can share with other colleagues in this repair electronic repair information newsletter.
