Kuhusu kifaa hiki cha kupigia hesabu
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.
Maswali yaliyoulizwa mara nyingi
Vikosi vya kuzuia rangi vimefanyaje kazi?
The first two (or three) bands give the significant digits, the next is a ×10ⁿ multiplier and the last is the tolerance. Brown-Black-Red-Gold = 1, 0, ×100, ±5% = 1 kΩ ±5%.
Bendi hiyo ya kuachilia mambo inamaanisha nini?
Uvumilivu ni umbali ambao upinzani halisi waweza kupotea kutoka thamani ya jina.
Njia za kubadili kanda huichumaje?
Huzunguka shabaha yako kwenye thamani iliyo karibu zaidi ambayo bendi za kuchimba zaweza kuonyesha, kisha huchagua ongezeko ili mashindano ya kusoma Étane za rangi zilezile ambazo ungesoma kutokana na mkinzani halisi wa thamani hiyo.
Kuna tofauti gani kati ya wakinzaji 4-, 5 na 6 walioachiliwa?
Mkinzaji wa safu nne ana bendi mbili za wadi; cave 5 inaongeza pensheni ya tatu kwa ajili ya uvumilivu mkali kama 1%; na cango la 6 laongezea kundi la mwisho la wapiga kura kuonyesha kiasi cha thamani inayoelea kwa kiwango fulani. Kwa ujumla, bendi zaidi zinamaanisha sehemu sahihi zaidi.
Ni upande gani wa yule mpinzani ninaosoma kwanza?
Anza kutoka kwa bendi iliyo karibu na mwisho na kusomwa kuelekea bendi inayopendelea uhuru, ambayo kwa kawaida ni dhahabu au fedha na kutenganishwa kidogo na wengine. ikiwa dhahabu au fedha imeketi kwenye mwisho mmoja, huo ndio ukanda wa uvumiliano, basi soma kutoka mwisho ule mwingine.
Vikundi vya dhahabu na fedha vinamaanisha nini?
In the multiplier position gold means ×0.1 and silver means ×0.01, giving sub-ohm values. In the tolerance position gold means ±5% and silver means ±10% — the two most common everyday tolerances.
Kwa nini 1788 mchana wangu unalingana kabisa na ule ujumbe?
The bands give a nominal value plus a tolerance window. A ±5% 1 kΩ resistor may legitimately measure anywhere from 950 Ω to 1,050 Ω, and temperature and age can shift it further, so a small mismatch on a multimeter is completely normal.
