What is the value of resistor color code?

What is the value of resistor color code?

The fourth band (or 5th for the 5-band and 6-band) indicates the tolerance values. Here, two colors are added (gold and silver). The 6th band for a 6-band type resistor is the temperature coefficient….Resistor Band Colors.

Color Value
Green 5
Blue 6
Violet 7
Grey 8

What are the colors of resistors?

Red 2 ± 2%
Orange 3
Yellow 4

How do you calculate resistor color code?

6 Band Resistor Color Code The formula for the three-band resistor color code is – 1st digit. 2nd digit. third digit x Multiplier = 1.0. 3 X100 = 10.3-kilo ohm ±5% 100 ppm/oc.

What is the resistor value?

Resistors. A resistor is a device that opposes the flow of electrical current. The bigger the value of a resistor the more it opposes the current flow. The value of a resistor is given in ohms and is often referred to as its ‘resistance’.

What color is a 470K resistor?

What does 1k ohm mean?

The value of the resistance is expressed as a number of ohms (the symbol Ω is used for ”ohm”). In this lesson, we work this out for a 1k Ω resistor where ”k” is the abbreviation for the prefix ”kilo”, meaning 1,000. So, a 1k Ω resistor has a value of 1,000 ohms and the number we will code is 1,000.

How do I know if I have a 330 ohm resistor?

Thus, for 330-ohm resistor, 1st digit is ‘ 3 ‘, ∴ look for color in a chart with value 3, then it’s your 1st color(say orange). The next 2nd digit is ‘ 3 ‘, ∴ look for color in a chart with value 3, then it’s your 2nd color (say orange).

What do the colors on resistors indicate?

The resistor color code indicates the electronic value of a resistor. Manufacturers devised the universal electronic color code rating system in the early part of the twentieth century because the bands of color were much easier to read on a small resistor than tiny print, and were also cheaper to produce.

How do identify resistor values?

First Step. The Red band of the resistance value is 2 and the brown band of the resistance value is 1 from the table. Second Step. From the table, the third orange band has value 1000. Multiply this value to 21 i.e. Third Step. Last is the Gold band having tolerance value in 5% (0.05) from the table.

How to find the resistor values?

Find the Value of Burnt Resistor by Four Simple Methods Method 1. Scarp the outer coating. Method 2. This method can also be used for finding the value of burnt resistor (s) (also, may be applied on connected resistors in the circuit) in case you don’t Method 3. Method 4.

What is the standard value of a resistor?

Typical resistor values lie in the range from 100 &OHgr to 10 k&OHgr with a matching tolerance of ±0.2% and a temperature coefficient of resistance of ±10 to ±200 ppm/°C. Diffused resistors are based upon the same fabrication geometry and techniques used to produce the active transistors on the silicon chip or die.
