Resistor color code 4 band black brown red blue gray 1 2 3 silver 100 red brown. 10 resistors are rarely used today see this page for a list of the more commonly used 5 gold tolerance band resistors.ġ0m 10m ohm resistor colour code. A resistor color code calculator to compute the resistance based on color codes or find the color codes based on a resistance value in ohms kilohms or megaohms. Resistor colour code standard resistor values ohms law resistors in parallel resistors in series. Resistor colour code standard resistor values ohms law resistors in parallel resistors in series delta y transformation calculator. For instance suppose you have a resistor that has a red violet brown color code.
Red 2 violet 7 27 brown x10 27 10 270 in this case you are holding a 270 ohm resistor.Ġ1w to 082w 10.
It is sometimes easier to remember the resistor colour code by using mnemonics or phrases that have a separate word in the phrase to represent each of the ten two colours in the code. If resistor has no fourth tolerance band then the default tolerance would be at 20.
