Resistor colour code

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 is a resistor color 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.

What are the Colours of resistor?

Brown± 1%
Red± 2%
Green± 0.5%
Blue± 0.25%
Violet± 0.1%
Grey± 0.05%
Gold± 5%
Silver± 10%

How do you read a resistor code?

The first two bands always denote the first two digits of the resistance value in ohms. On a three or four-band resistor, the third band represents the multiplier. This multiplier will basically shift your decimal place around to change your value from mega ohms to milliohms and anywhere in between.

Why we use 1K resistor?

Commonly used in breadboards and other prototyping applications, these 1K ohm resistors make excellent pull-ups, pull-downs and current limiters. These thick-lead versions of the resistors fit snugly into a breadboard with very little movement, so you should have few to no issues using them in your next project!

What is color coding?

Color coding in the workplace mainly concerns the safety and disaster preparedness of the workforce. The concept consists of assigning different colors to indicate various risks, dangers, and safety hazards either up-close or from a distance (even when vision is compromised and reading safety signs could be difficult).

What color is a 50 ohm resistor?

Color	Value
Brown	100 ppm/ºC
Red	50 ppm/ºC
Orange	15 ppm/ºC
Yellow	25 ppm/ºC

How do you read a 5 color resistor?

If the colors on a 5 band resistor is in this order: brown, green, red, blue and violet (as shown in figure). The values of color bands will be like this: Brown = 1, Green = 5, Red = 2, blue = 106, Violet = 0.10%.

What is a resistor symbol?

The value of a resistor is measured in ohms and represented by the Greek letter capital omega (Ω). The resistance value is specified in ohms, the standard symbol is “R” or Ω. Resistor values are often stated as “k” (kilo, or times 1,000) or “M“, (meg, or times 1,000,000) for convenience.

What are the 4 types of resistors?

Types Of Resistors

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

What color is a 24K resistor?

24K Ohm Resistor Color Code: Red, Yellow, Orange, Golden.

What color is a 3 ohm resistor?

3 Ohm Resistor Color Code: Orange, Black, Golden, Golden.

How do you read color?

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. The color values are defined in values between 00 and FF (instead of from 0 to 255 in RGB).

What is resistor number?

Resistor values are usually shown using coloured bands, each colour represents a number as shown in the table. Most resistors have 4 bands: The first band gives the first digit. The second band gives the second digit. The third band indicates the number of zeros.

What do resistor numbers mean?

The Three and Four Digit Systems In these systems, the first two or three digits indicate the numerical resistance value of the resistor and the last digit gives a multiplier. The number of the last digit indicates the power of ten by which to multiply the given resistor value.

What is 2K resistor?

2K Ohm Resistor Color Code: Red, Black, Red, Golden. Resistance: 2K Ohm, Power Rating: 0.25 Watt, Approximate Maximum Current: 11.18mA.

What is 1M resistor?

1M Ohm 0.25W Metal Film Resistor 1% - High Quality Resistance: 1M Ohm, Power Rating: 0.25 Watt, Approximate Maximum Current: 0.5mA ..

What are 3 purposes of a resistor?

Resistors are used for many purposes. A few examples include limiting electric current, voltage division, heat generation, matching and loading circuits, gain control, and setting time constants.

How do I find my colour code?

Look for your vehicle information sticker to find your color code. Usually, it's located on your dash, inside your door jamb, or in the trunk. If you can't find your vehicle information sticker, try looking up your VIN on your car title or insurance. Then, you can contact your dealership.

Why are color codes used?

Used as an effective and quick means of identification, colour coding is used in everyday life from traffic lights to brand awareness to professions including electricians who rely on colours for wire and resistance recognition.
