Comprehension resistor color code is really very important if you want to determine the resistor values of the certain resistor. Every resistor color band represents a quantity exactly where you could refer to code beneath to help you to acquire the regular resistor worth. The resistor coding act being a resistor calculator and with examples given, it would not consider you a very long time to understand it.
0=black, 1=brown, 2=red, 3=orange, 4=yellow, 5=green, 6=blue, 7=violet, 8=grey, 9=white, gold=5% and silver=10%
Red, red, orange, gold = 22 multiply by one (orange equal to 3 zero), so you get 22 multiply by 1000 =22000 ohms or 22 kilo ohms with tolerance of +/-5% (gold).
Blue, grey, brown, gold = 68 multiply by 1 (brown equal to one zero), so you get 68 multiply by 10 = 680 ohms with tolerance of +/- 5 %.
Brown, black, yellow gold = ten multiply by 1 (yellow equal to 4 zero), so you get ten multiply by 10000 =100000 ohms or a hundred kilo ohms with tolerance of +/-5%.
Yellow, violet, gold, gold = 47 multiply by 0.1 (gold at 3rd band), so you receive 4.seven ohms with the tolerance of +/-5%
Orange, orange, silver, gold =33 multiply by 0.01 (silver at third band), so you get 0.33 ohms with tolerance of +/-5%.
In electronic repair, most of the time i arrived across five band resistor color code. The objective of using the 5 colour band resistor in a circuit is that it delivers a much more correct value evaluate to the four color band. By way of example to be able to get the worth of 22.6kohm, with four colors band resistor you are going to not have the ability to discover it. Essentially the most you can get is 22k (red, red, orange and gold).
If with the 5 colour band you will be in a position to determine it (red, red, blue, red, brown) the last colour that is brown symbolize 1% tolerance. When you open up an analog multimeter you are going to comprehend whatIi suggest. Most of the resistor color code circuits inside the multimeter are utilizing 5 color bands. Why? Given that the studying that you simply get anytime you measure current, voltage or ohm, the panel will display the nearest worth. For instance, in the event you measure a 9v battery the needle will point to may be eight.9v, 9v, or 9.one volt. If that particular multimeter was developed making use of 4 colors band resistors the outcome that it gets might be 8.5v, 9.5v or perhaps 10 volt. To put it differently using 5 colour band resistor would be to produce a circuit alot more precise and output the wish outcome as what the engineers want it to be.
In the event you come throughout any wire wound resistor, you can find numbers printed on the resistor and every coding represents a resistor value. Beneath will be the formulas which you can use to come across out the precise resistor values:R82 is .82 ohm, 15R2 is 15.2 ohm, 100R is one hundred ohm, 10K is 10 kilo ohm, 2K7 is 2.seven kilo ohm, and 2M2 is two.two mega ohms. Hope you uncover this resistor color code post useful and have the ability to determine resistor worth within the shortest time.
