3 band resistor color code calculator

The values of 3-band resistors have a tolerance of ±20% and are commonly used by hobbyists or when the resistance value is not critical. For a 1R0 (1 Ω) resistor with 3 bands, the colors will be brown, black and gold. The resistance value will fall between 1.2 Ω and 0.8 Ω.

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.

What does the 3rd band mean on resistors?

The third band is called a Multiplier, this means the number of zeros you add after the first two digits to get the Ohm value (example: brown = 0). So one zero is added after the first two numbers. Therefore 220 ohms is the resistance value of the resistor.

What color is a 3K Ohm resistor?

3K Ohm Resistor Color Code: Orange, Black, Black, Brown, Brown.

What is the colour of third band?

The third band is brown, which means that the multiplier is 1.

How do you calculate resistor bands?

To calculate the resistance value, you need to group the values of the significant digits bands — i.e., the values of the first two or three bands from the left, depending on the total number of bands. Then you need to multiply that value by the multiplier to get the resistance value of the resistor.

What color is a 470 Ohm resistor?

470 Ohm 0.5W High Quality Carbon Film Resistor (CFR) with ±5% Tolerance and Tin Plated Copper Leads. 470 Ohm Resistor Color Code: Yellow, Violet, Brown, Golden.

How do you read resistor color bands?

Also indicates the reading direction the first band is red so the first digit value is two the

How do I calculate resistance?

R = V ÷ I Question What is the resistance of the lamp? To calculate the resistance of an electrical component, an ammeter is used to measure the current and a voltmeter to measure the potential difference. The resistance can then be calculated using Ohm's Law.

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.

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 do resistor colors mean?

A gold band represents a tolerance of +/-5%, and a silver band represents a tolerance of +/-10%. If no tolerance band is present, the tolerance is +/-20%. There are some resistors with smaller tolerances, but gold and silver are the most common tolerance band colors.

What is the colour code of 1K ohm?

A 1K Ohm resistor can be identified via resistor color codes of Brown-Black-Red-Gold or Brown-Black-Black-Brown-Gold.

What color is a 4.7 K resistor?

4.7K Ohm Resistor Color Code: Yellow, Violet, Red, Golden.

What color is a 2.7 K resistor?

2.7K Ohm Resistor Color Code: Red, Violet, Red, Golden. Resistance: 2.7K Ohm, Power Rating: 2 Watts, Approximate Maximum Current: 27.22mA ..

What is the value of a 3 band resistor that has a color code of BRN BLK red?

Once you find the values for the first two bands, for example, if we have a red band and a black band, then the values will be 2 and 0. Put these two numbers together and you'll get the number 20.

How do you tell which is the first band on a resistor?

The first band gives us the first digit of our resistor. The second band gives us the second value

How do you read a 4 bands resistor?

The first few bands represent resistance values then the farther band will represent a multiplier

How do I calculate current?

The current is the ratio of the potential difference and the resistance. It is represented as (I). The current formula is given as I = V/R.

What color is a 2.2 K ohm resistor?

What is 2.2k ohm Resistor color code for 4-band? The color code of 2.2 k resistor is Red-Red-Red-Gold. From the above resistor color code table, you will find that Red stands for 2 and Red for 2. The third band is Red, so it means a multiplier value of 2 (100).
