Resistor code calculator

Reading and Determining the Resistor Value Hold the resistor with the gold or silver band to the right and read the color codes from the left to the right. Select the color codes from the bands on the resistor. Read the colors from left to right. The resistance value based on the color code provided is now displayed.

How do you calculate resistor color code?

Calculating Resistor Colour Code Values For example, a resistor has the following coloured markings; Yellow Violet Red = 4 7 2 = 4 7 x 102 = 4700Ω or 4k7 Ohm. The fourth and fifth bands are used to determine the percentage tolerance of the resistor.

How do you calculate a 5 band resistor?

Let's take an example of a 5-band resistor with the colors given in the above image (brown, green, red, black and gold). So according to the formula the resistance will be: 152 * 1 = 152 Ohms with 5% tolerance.

What is a resistor coding?

Resistor Color Coding uses colored bands to quickly identify a resistors resistive value and its percentage of tolerance with the physical size of the resistor indicating its wattage rating.

How do you read a 4 digit resistor?

Resistor Code Format Similar to the three digit EIA, the four digit format uses the beginning values to indicate the significant digits while the last digit is the multiplier. 'R' is used to indicate the position of a decimal point. The four digit format allows for higher precision.

What color is a 47K resistor?

Resistance		47K ohm
Color Code		Yellow / Violet / Orange / Gold
Type		Carbon Film
Voltage	Maximum Operating	350V
Polarization		None

What is resistor color code chart?

Therefore, the first three bands indicate the significant digits, the fourth band is the multiplication factor, and the fifth band represents the tolerance. For the example shown here: brown (1), yellow (4), violet (7), black (x 100 = x1), green (0.5%) represents a 147 Ω resistor with a 0.5% tolerance.

What color is a 470 ohm resistor?

470 Ohm 2W High Quality Carbon Film Resistor (CFR) with ±5% Tolerance and Tin Plated Copper Leads. 470 Ohm Resistor Color Code: Yellow, Violet, Brown, Golden.

What is the color code for a 220 ohm resistor?

Hence the colour code of 220 ohm resistor will be – red, red and brown.

What voltage is a 5 ohm resistor?

For the 5 Ohm Resistor , V = 5 × ( 1 / 4 ) = ( 5 / 4 ) Volts.

How do I identify a resistor band?

The colors on the first 2 or 3 bands correspond to numbers from 0 to 9, which represent the significant digits of the resistor's ohmic value. The last band gives the multiplier. For example, a resistor with brown, green and green bands is rated at 15 mega-ohms (15,000,000 ohms).

Can we use 4 band resistor instead of 5 band?

Yes, you can of course substitute a 4 band for a 5 band resistor, and vice versa, as long as the values of its resistance, voltage and tolerance match the needs of the circuit and you're willing to pay the price hike for high-precision resistors.

What are the 4 types of resistors?

Types Of Resistors

Thermistors.
Varistor Resistors.
Photo Resistor or LDR (Light Dependent Resistors)
Surface Mount Resistors.

What is a commonly used resistor code system?

The most commonly seen codes are the three and four digit system and an Electronic Industries Alliance (EIA) system called EIA-96.

How do you read a color code?

Hex color codes start with a pound sign or hashtag (#) and are followed by six letters and/or numbers. The first two letters/numbers refer to red, the next two refer to green, and the last two refer to blue. ... For example:

A=10.
B=11.
C=12.
D=13.
E=14.
F=15.

How do you decode a 4 band resistor?

In the standard four band resistors, the first two bands indicate the two most-significant digits of the resistor's value. The third band is a weight value, which multiplies the two significant digits by a power of ten. The final band indicates the tolerance of the resistor.

How are resistors numbered?

Resistor colour code The first band gives the first digit. The second band gives the second digit. The third band indicates the number of zeros. The fourth band shows the tolerance (precision) of the resistor but this may be ignored for almost all circuits.
