Ku saabsan Kalkaaliyahan
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.
Su'aalaha badanaa la isweydiiyo
Sidee u shaqeeyaan bands resistor midab?
Labada (ama saddex) bands ugu horeysay siiyaan lambarrada muhiimka ah, ka dambeeya waa ×10ⁿ multiplier iyo ugu danbeeyay waa dulqaad. Brown-Black-Red-Gold = 1, 0, ×100, ±5% = 1 kΩ ±5%.
Maxaa ka dhigaya band tolerance macnaheedu yahay?
Tolerance waa sida fog ee diidmada dhabta ah ka mid ah qiimaha magaciisa ka soo jeedo. A ± 5% 1 kΩ diidmada ka mid ah 950 Ω ilaa 1050 Ω.
Sidee bay qaabka ka soo horjeeda doortaan bands?
Waxay ku wareegsan tahay ujeeddadaada qiimaha ugu dhow ee digirta digirta ay muujin karaan, ka dibna dooran kartaa multiplier si akhriska u dhigma - midabka isku mid ah waxaad akhrin lahayd ka dibna aad u akhrido ka dibna aad u akhrido ka dibna aad u akhrido ka dibna aad u akhrido ka dibna aad u akhrido.
Maxay tahay farqiga u dhexeeya 4-, 5- iyo 6-band resistors?
A 4-band resistor waxaa leh laba digit bands; a 5-band ku daray digit saddexaad ee dulqaad adag sida ± 1%; iyo 6-band ku daray band heerkulka-coefficient ugu dambeeyay oo muujinaya sida qiimaha u dhaqdhaqaaqa heerka. Bands badan guud ahaan macnaheedu waa qayb ka mid ah in ka badan oo sax ah.
Waa maxay dhamaadka resistor aan akhriyo hore?
Bilow ka band ugu dhow dhamaadka iyo akhriso dhinaca band tolerance, taas oo caadi ahaan dahab ama lacag ah oo si yar uga kala duwan oo ka mid ah kuwa kale. Haddii dahab ama lacag ku fadhiya dhamaadka mid ka mid ah, taas oo ah band tolerance, sidaas akhriso ka dhamaadka ka soo horjeeda.
Maxaa ka dhigan yihiin bands dahab iyo lacag ah?
In booska multiplier dahab macnaheedu waa ×0.1 iyo lacag macnaheedu waa ×0.01, siin sub-ohm qiimaha. In booska dulqaad dahab macnaheedu waa ±5% iyo lacag macnaheedu waa ±10% - laba ka mid ah tolerances ugu badan ee caadiga ah maalin kasta.
Maxaa aan ka difaacay miisaanka aan si toos ah ugu habboon yahay koodhka?
Bands bixiyaan qiimaha magacyada iyo sidoo kale daaqadda dulqaad. A ± 5% 1 kΩ resistor waa sharci ahaan la xisaabin karaa meel kasta oo ka mid ah 950 Ω ilaa 1,050 Ω, iyo heerkulka iyo da'da ka sii dhaqaaqi kartaa, sidaas darteed isku mid ah yar on multimeter waa si buuxda caadi ah.
