3 band resistor color code calculator code#
Our color code calculator runs this check automatically for you, and if the result is not a standard value, it will display a small tip. This is a necessary step especially with five and six banded metal film resistors. If it isn't, then try reading it again starting from the other end and check again.

You should always attempt to work out the value, then check your result against a resistor value chart to see if it's listed there. What happens, if I start reading from the wrong end? Also, the 3rd color for 4-band resistors will be blue (10 6) or less and the 4th color for 5 band resistors will be green (10 5) or less, as basic resistor values range from 0.1 Ohm to 10 Mohms. Hold the resistor with the closely grouped bands to your left and read the resistor from the left to the right.Ģ.) With 5% and 10% resistors the procedure is simple: hold the resistor with the silver or gold band to the right and read the resistor from the left to the right.ģ.) The first band can't be silver or gold, so if you hold such a resistor you'll know instantly where to start. The short answer: you'll know that from experience! But there are some rules you can follow:ġ.) Some resistors have the color bands grouped together and/or close to one end. Red, red, brown is a 220 ohm, 20% resistorīrown, black, orange is a 10k, 20% resistor They will be calculated using the 4 band rule (digit, digit, multiplier). You don't have to enter the 4th band, as 20% resistors don't have a tolerance ring. Resistors with 6 bands are basically 5-band resistors with an additional ring indicating the reliability or the temperature coefficient.
