510k Ohm Resistor Color Code
Resistor color code is a color code to indicate the resistance of that resistor. Resistor color code can be formed with 3, 4, or 5 color bands. Each band has their own number to form a resistance number. The body color doesn't have any meaning.
The figure below shows the color coding of the 510k Ohm resistor with a tolerance of ±10%. The color code of resistor with 4 bands will be with colors of the bands are , , and .
How To Read a Resistor Color Code for 4-band resistor
The color of the first band indicates the value of the first significant digit. The first band is , which corresponds to the value .
The color of the second band indicates the value of the second significant digit. This band is , which corresponds to the value . This is added to the right of the first digit (from band one). Therefore the digits from band one and band two are: .
The third color band represents a decimal multiplier by which the first two digits must be multiplied to obtain the resistance value of the resistor. Takes the digits and multiplies them by a value given by this band. The actual multiplier is 10n, where n is the value of the band color. In this case, the third band is which corresponds to the number . Therefore the multiplier is 10 = 1.
So the total value of the resistance given by the colors is x 10 Ω = 0 Ω.
The fourth band indicates the tolerance values. A band is used in this example, giving us a tolerance of 10%.
As a result, the resistance value of the resistor with the color bands of is 510k Ohm with ±10% tolerance.
