What is Colour code system for resistor?

The four band color code is the most common variation. These resistors have two bands for the resistance value, one multiplier and one tolerance band. In the example shown here, the 4 bands are green, blue, red and gold. By using the color code chart, one finds that green stands for 5 and blue for 6.

What is Colour coding method?

Resistor Colour Coding uses coloured bands to easily identify a resistors resistive value and its percentage tolerance. There are many different types of Resistor available which can be used in both electrical and electronic circuits to control the flow of current or to produce a voltage drop in many different ways.

What are the color codes of resistors?

Black: 0

Why is colour code used for resistors?

Components and wires are coded with colors to identify their value and function . 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 do the colours on the resistor mean?

Resistor body colors white and blue are used to mark non-flammable resistors and fusible resistors. If you encounter tjis type of resistor in the circuit do not replace it with normal reistor because this would cause fire danger is something goes wring in the circuit.

What is the history of the resistor color code?

The resistor colour code was invented in the 1920s by the Radio Manufacturers Association (RMA). All leaded resistors with a power rating up to one watt are marked with colour bands. They are given by several bands and together they specify the resistance value, the tolerance rate and sometimes the reliability or failure rates.
