Nezve iyi kalkulator
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. The calculator returns the nominal resistance, the tolerance and the guaranteed value range. The calculator also shows the value of the resistor color code. As a working example, the classic brown-black-red-gold band pattern reads as digits 1 and 0, a ×100 multiplier and ±5% tolerance: (10 + 0) × 100
Zvimwe zvinobvunzwa zvakanyanya
Maitiro ekushanda kweresistor color bands?
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%.
Chii chinonzi tolerance band?
Kuchengeteka ndechokuti sei kure chokwadi kuremekedza anogona kubuda kubva mubhadharo mashoko. A ± 5% 1 kΩ resistor anogona kuongorora chero kupi kubva 950 Ω kuti 1050 Ω.
Maitiro ekudzokorora modhi anotora sei mabhaisikopo?
It rounds yako chinangwa kune yakanakisisa kukosha digit mabhandi anogona kutaura, uye wosarudza multiplier kuti kuverenga makwikwi - zvakafanana mavara iwe uchaverenga off a real resistor yezvakaipa.
Ndeupi musiyano pakati pe4-, 5- uye 6-band resistors?
A 4-band resistor ane maviri digit mabhaisikopo; a 5-band anowedzera wechitatu digit for tighter tolerance se±1%; uye a 6-band anowedzera a final tembiricha-coefficient mabhaisikopo kuratidzwa sei kukosha drifts per degree.More mabhaisikopo zvinoreva zvakajeka chikamu.
Chii chisina kumbobvira chisina kumbobvira chisina kumbobvira chisina kumbobvira chisina kumbobvira chisina kumbobvira chisina kumbobvira chisina kumbobvira?
Kutanga kubva band nearest rimwe kupera uye kuverenga kuseri tolerance band, iyo inowanzo gold kana silver uye zvishoma zvakasiyana kubva kuseri. Kana gold kana silver kugara pamwechete, kuti ndiyo tolerance band, saka kuverenga kubva kumashure.
Chii chinonzi Gold and Silver Bands?
Mumultiplier nzvimbo gold zvinoreva ×0.1 uye silver zvinoreva ×0.01, kupihwa sub-ohm hunhu.Mu tolerance nzvimbo gold zvinoreva ±5% uye silver zvinoreva ±10% - maviri anonyanya kuzivikanwa zuva nezuva tolerance.
Nei yangu yakaongororwa resistance ichienzaniswa nekodzero?
Bands kupa zita kunaka pamwe ne tolerance window. A ± 5% 1 kΩ resistor anogona zvakachengeteka kuongorora chero kupi kubva 950 Ω kuti 1,050 Ω, uye tembiricha uye makore anogona kuchinja ichi pamusoro, saka a zvishoma kusingaenzaniswi pa multimeter ichokwadi.
