The resistor color code is the scheme of coloured bands painted on a resistor to show its value, used because the parts are too small to print numbers on. Reading left to right, the first bands are significant digits, the next band is a power-of-ten multiplier and the last band is the tolerance. For a 4-band part the value is (10 × digit1 + digit2) × 10^multiplier ohms; 5- and 6-band parts add a third significant digit for tighter precision (and, on 6-band parts, a temperature-coefficient band). Each colour maps to a fixed number: black 0, brown 1, red 2, orange 3, yellow 4, green 5, blue 6, violet 7, grey 8, white 9, with gold and silver serving as ×0.1 and ×0.01 multipliers or ±5% and ±10% tolerances.
As a worked example, the classic brown-black-red-gold band pattern reads as digits 1 and 0, a ×100 multiplier and ±5% tolerance: (10 + 0) × 100 = 1,000 Ω, i.e. a 1 kΩ ±5% resistor whose true value lies anywhere from 950 Ω to 1,050 Ω. Decode any part by selecting the colour of each band from the drop-downs and the calculator returns the nominal resistance, the tolerance and the guaranteed value range.
Switch to reverse (encode) mode to go the other way: type a target resistance and the tool rounds it to the nearest value the digit bands can express, chooses the multiplier to match, and lists the band colours you would read off a real resistor of that value — handy when you have a schematic value and need to find or verify the physical part on your bench.
Mafunso ofunsidwa nthawi zambiri
Kodi ndi chiyani chimachititsa kuti ma bands amtundu wa resistor azigwira ntchito?
Kuyamba awiri (kapena atatu) mafilimu amapereka digits zofunika, m'tsogolo ndi ×10ⁿ multiplier ndi yapitayo ndi kukhulupilira. Brown-Black-Red-Gold = 1, 0, ×100, ±5% = 1 kΩ ±5%.
Kodi chimatanthauza chiyani band tolerance?
Kukana ndi momwe mbali yachikhalidwe yotsutsana imatha kuchoka pa malire a ± 5% 1 kΩ resistor ingawerengere chilichonse kuchokera ku 950 Ω mpaka 1050 Ω.
Kodi njira yosinthira amasankha bwanji ma bands?
Imakhala yozungulira yoyenera yanu ku mtengo wotsika kwambiri womwe digito amatha kufotokoza, kenako amasankha multiplier kuti kuphunzira kumagwirizana - mitundu yofanana yomwe mungawerengere pa resistor yachikhalidwe ya mtengowo.
Kodi pali kusinthana pakati pa 4-, 5- ndi 6-band resistors?
A 4-band resistor ali ndi awiri digito mafilimu; a 5-band amawonjezera digito yachitatu kwa tighter zomvetsera monga ± 1%; ndi 6-band amawonjezera mapeto kutentha-coefficient mafilimu kusonyeza mmene mtengo drifts pa degre.
Kodi m'mphepete mwa resistor ndiyenera kuwerenga koyamba?
Kuyambira pa band kumapeto kwa m'mbali ndi kuwerenga kudzera tolerance band, amene nthawi zambiri ndi siliva kapena siliva ndi pang'ono kugawidwa kuchokera kumapeto ena. Ngati siliva kapena siliva ali pa m'mphepete, kuti ndi tolerance band, kotero kuwerenga kuchokera kumayambiriro.
Kodi n’chiyani chimatanthauza zovala zagolide ndi zovala zasiliva?
M'malo osiyanasiyana, siliva amatanthauza ×0.1 ndi siliva amatanthauza ×0.01, kupatsa matanthauzo a sub-ohm.M'malo ovomerezeka, siliva amatanthauza ±5% ndi siliva amatanthauza ±10% - ma tolerance awiri odziwika kwambiri tsiku ndi tsiku.
N'chifukwa chiyani kukana kwabwino koyenera kugwirizana ndi code?
Ma bands amapatsa tanthauzo la dzina limodzi ndi zenera la tolerance. ± 5% 1 kΩ resistor angathe kuyerekezera komweko kuchokera ku 950 Ω mpaka 1,050 Ω, ndipo kutentha ndi zaka zingathe kusinthidwa, kotero kuti kusokonezeka kwazing'ono pa multimeter ndi koyenera.
