What is a resistor?
Resistors are the passive additives used withinside the electric circuits to lessen the waft of electrical present day to sure level. The cappotential to limition the waft of electrical present day is known as resistance. The resistors with excessive resistance price will restricts huge quantity of electrical present day while the resistors with low resistance price will restricts handiest a small quantity of electrical present day. The resistance of a resistor is measured in ohms.

What is a Resistor Color code?
Generally, code refers to a illustration of records in some other shape via way of means of the usage of symbols, alerts, and letters for the functions of secrecy. Here, the alerts or symbols act as codes. In the same manner, in resistors we use exclusive shades as codes to specify the resistance (records) of the resistor. Here, the exclusive shades lined at the resistor act as codes.

The Resistor color codes also are used to specify the tolerance and reliability of the resistor. We also can without delay discover the resistance price of a resistor via way of means of the usage of ohmmeter.

in resistors we use exclusive shades as codes to recognize the resistance (records) of the resistor.
The Resistor color codes are used now no longer handiest in resistors however additionally in different digital additives which includes capacitors and inductors.

Specifying the values or scores of digital additives such resistors, capacitors, and inductors via way of means of the usage of the Color codes revealed on them is known as digital Color code device. The digital Resistor Color code device became advanced withinside the early Twenties via way of means of the radio manufactures association, that is now a part of Electronic Industries Alliance (EIA).

The Color-coding is achieved handiest withinside the constant resistors however now no longer in variable resistors due to the fact the Color coding method suggests handiest a set resistance price. The variable resistors have various resistance. Hence, it isn’t always feasible to apply the Color coding method in variable resistors.

Why Color codes are utilized in resistors as opposed to without delay printing the resistance price?
Printing the numbers on huge digital additives could be very easy, however it’s far very tough to print the numbers or resistance values on tiny additives. Hence, as opposed to without delay printing the numbers, we print the Color codes or Color bands. However, via way of means of the usage of the modern-day printing era we will without delay print the numbers on resistors.

The Color coding method has a few drawbacks. For blind people, it’s far not possible to discover the resistance of the resistor, due to the fact they can not see the Colors lined at the resistor.

Another downside is spotting the distinction among shades in an overheated resistor could be very tough. When the resistor is overheated, the Colors at the resistor modifications slightly. Therefore, it turns into not possible to understand the distinction among brown Color and purple Color or brown Color and orange Color.

Representing the resistance of a resistor via way of means of the usage of Color bands
In a Color coding method, the resistors price is marked at the resistors frame via way of means of the usage of shades. The shades painted at the resistors frame are known as Color bands. All the Color bands painted at the resistor frame are used to suggest the resistance price and tolerance. Each Color at the resistors frame represents a exclusive variety.

The Color bands of resistors are essentially of 3 types: four band resistor, five band resistor, and six band resistor. In order to discover the resistance of a resistor, we want to decode the Colors painted at the resistors frame. The deciphering modifications primarily based totally upon the variety of Color bands painted at the resistors frame.

A four band Color code resistor has three Color bands on left aspect and one Color band on proper aspect
The three Color bands at the left aspect are grouped collectively to suggest the resistors resistance price and the 4th Color band at the proper aspect suggests the tolerance of the resistor.

What is tolerance? “Tolerance is the version withinside the resistance of a resistor from its real resistance. The resistors of excessive tolerance have excessive version withinside the resistance. The resistors of low tolerance have low version withinside the resistance. For example, a resistor that has a tolerance of five% may also range five% of its resistance from its real resistance price. Similarly, a resistor that has a tolerance of 8% may also range 8% of its resistance from its real resistance price. Tolerance of a resistor is typically laid out in percentage.”

The 1st Color band at the resistor suggests the first widespread price or 1st digit of the resistors resistance and the second Color band suggests second widespread price or second digit of the resistors resistance. The third Color band is the decimal multiplier and the 4th Color band suggests the resistors tolerance.

The 1st and second Color bands collectively make up a 2 digit variety and the third Color band or multiplier is elevated with this 2 digit variety to gain the resistance price of the resistor.

If the 4th Color band or tolerance band is left blank, it’s far taken into consideration because the three band resistor and the tolerance for the three band resistor is believed to be 20%.

Resistors which might be synthetic for navy use may additionally encompass an additional band known as fifth band which suggests resistor failure fee.
