Visit the Tables page to view reference tables such as Maximum Ampacity for Current-Carrying Conductors. To calculate wire ampacity for a circuit, use the Wire Ampacity Calculator or the Advanced Wire Ampacity Calculator.įor long conductor runs where voltage drop may be an issue, use the Voltage Drop Calculator to determine proper conductor sizing and maximumĬircuit length. MELF and Leaded Resistor Products E96 Series and E192 Series. To calculate wire size for a circuit, use the Wire Size Calculator or the Advanced Wire Size Calculator. The values of color bands will be like this: Green 5, Brown. Produces a resistance value of 123 * 100 = 12.3 kΩ with a ± 5% tolerance. If the colors on a 6 band resistor is in this order: green, brown, violet, black, gold and orange. Band 4: Multiplier (determines order of magnitude)įor example, a resistor with a color band pattern of brown, red, orange, red, gold yields the first digit as 1, the second digit as 2, the third digit as 3, and a multiplier of 10,000.Band 3: Third significant figure (additional digit of precision).Band 1: First significant figure (left-most digit).Tolerance: Gold Band 5: Related Articles. Resistance values can be calculated from a 5-band resistor color code as follows: A resistor is identified by its pattern of color of bands. 4 Band Colour Code: Colour Code: Brown, Black, Orange, Gold: Multiplier.
