Although the colour code isn't always simplest for resistors, the capacity to study the resistor color code is greater required amongst engineers and scientists. This handy index become created with the aid of using Radio Manufactures Association (now a part of Electronic Industries Alliance) in early 1920s. It is difficult to inform a number of hues and which aspect have to shows the tolerance. In fact, the tolerance of resistors withinside the 4th or fifth bands are from time to time prominent with the aid of using spacing or width of the band. This web page offers the way you study the 4th-, fifth-, and 6th-band resistor colour codes, and the associated statistics on resistors.

Various resistors and the properties
There are many styles of resistors for diverse uses.
Film kind resistors
These resistors are crafted from small rods of ceramic lined with resistive substances. The tough cost of resistance is decided with the aid of using the form of the center material; then, a skinny spiral groove reduce with the aid of using a laser or diamond cutter at the floor adjusts the excellent cost of resistance. It is connected to metallic caps with leads, and lined with an insulated layer to be finished as a retailing resistor.

Carbon Film resistors
carbonThe center rod of the resistors is lined with carbon. These resistors are generally used and the bought inexpensively.
Metal movie resistors
metalThe center rod of the resistors is deposited with metallic together with nickel alloy. The temperature coefficients are very small, and they may be used for noticeably correct circuits.
Metal oxide movie resistors
metallic oxideThe center rod of the resistors is deposited with metallic oxide, together with tin oxide. These resistors can take care of greater energy than different movie resistors.
Wirewound kind resistors
The resistors are made with a ceramic or glass rod, an insulator and resistive twine, together with the alloy of Nickel and Chromium (Nichrome) or the alloy of Copper, Nickel, and Manganese (Manganin). The cost of resistance is adjusted with the aid of using the quantity of the twine wound across the ceramic or glass rod. The values of resistance are commonly small and they may be smooth to be heated; however, they are able to address big quantities of energy because of warmness-resistant holders.
Cement resistors
cementThese resistors are made with resistive twine or metallic oxide movie blanketed with the aid of using silicon resin (cement), that's inflammable although it will become very hot.
Metal clad resistors
These resistors are housed in a thick alminum case to save you from damage, humidity, pressure, and warmness. They also are top notch at short-time overload.
Multiple kind resistors
The Through Hole resistor carries a couple of resistors with a couple of leads. It is handy to apply it whilst a couple of resistors ought to be related to a couple of terminals in a restricted room on a bread board.

The impartial resistor array carries every separated resistor. The bussed resistor array carries related resistors with one not unusualplace terminal as proven withinside the figure.
Resistor arrays (networks) [SIP type]
array 4-siparray 8-sipSIP stands for Single Inline Package. An instance is proven in a photograph.
Resistor arrays (networks) [DIP type]
array dipDIP stands for Double Inline Package. An instance is proven in a photograph.
Other styles of resistors
Chip resistors
chipThese are made with the aid of using floor mount technology, and they may be from time to time referred to as SMF resistors. The length could be very small. It is set 1-mm wide (0.04 inches).
Variable resistors
variableThese resistors can regulate the cost of resistance constantly in the certain range.
Audio resistors
audioThis resistor is made mainly for high-give up audio amplifiers. The simple shape is just like a movie resistor, however the substances used are magnet unfastened to decrease disturbance of audio properties. This is likewise top notch at warmness dissipation.
