Bu hasapçy hakda
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.
Köp soralýan soraglar
Rezistor reňk bandlary nädip işleýär?
Ilki iki (ýa-da üç) bandlar manyly rakamlary berýär, soňra gelen ×10ⁿ köpeltgiçi we soňky tolerans. Brown-Black-Red-Gold = 1, 0, ×100, ±5% = 1 kΩ ±5%
Tolerans band näme?
Tolerans, real resistor nominal bahadan näçe uzakda galmak mümkin. A ±5% 1 kΩ resistor can measure anywhere from 950 Ω to 1050 Ω.
Ters Mody Bandlary Nädip Saýlaýar?
Bu seniň maksatyňy iň ýakyn bahasyna tozlap çykarýar, onda okap durmak üçin köpeltgiçi saýlap alýar - şol bahanyň akyly rezistoryndan okajak reňkler.
4-, 5- we 6-band resistorlar arasyndaky tapawut näme?
4-band resistor iki rakam bandy bar; 5-band üçüncü bir rakam ekleýär ±1% ýaly dar toleranslar üçin; we 6-band bir temperatura-koeffisient bandy ekleýär derecede neçe bahanyň öçüp gidendigini görkezmek üçin. Daha köp bandlar esasan has dogry bir parçany aňladýar.
Rezistoryň haýsy uçury öňe okalýar?
Start from the band nearest an end and read toward the tolerance band, which is usually gold or silver and slightly separated from the rest. If gold or silver sits at one end, that is the tolerance band, so read from the opposite end.
Altyn we kümüş bandarlar näme aňladýar?
Çikmeçiň pozisiýasynda altyn ×0.1 we kümüş ×0.01 manysyny berýär, sub-ohm bahalary berýär. Tolerans pozisiýasynda altyn ±5% we kümüş ±10% manysyny berýär - iki iň köp ulanylýan her gün toleranslar.
Näme üçin meniň ölçeýän garşylygym kod bilen doly gabat gelmeýär?
Bandlar bir nominal baha bilen bir tolerans äpişgesini berýär. ±5% 1 kΩ rezistor 950 Ω dan 1,050 Ω aralygynda her ýerde ölçemek mümkin, we temperatura we ýaş ony has uzakda üýtgetmek mümkin, şonuň üçin multimetrdäki kiçijik bir meňzeşlik doly normal.
