I-Calculator yekhodi lombala we-Resistor
Ukufaka ikhodi 4/5/6-band resistor imibala eyinhlanganisela ku-value — noma ushintshe i-value ibe yi-bands.
Iziphetho zivuselelwa uma ubhala.
Malunga nale khadi
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.
Imibuzo ebuzwa kaningi
Usebenza kanjani umdwebo we-resistor?
I-bands yokuqala emibini (noma emithathu) inikeza ama-digits abalulekile, olandelayo yi-×10ⁿ multiplier futhi okugcina yi-tolerance. Brown-Black-Red-Gold = 1, 0, ×100, ±5% = 1 kΩ ±5%.
Yini okushoyo i-band of tolerance?
Ukubekezela kukhombisa ukuthi ikuphi ukumelana okungokoqobo kungahamba phambili kusuka kuxabiso elibizwa ngokuthi. ±5% 1 kΩ ukumelana kungalinganiselwa kuphi naphi kusuka ku-950 Ω kuya ku-1050 Ω.
Indlela yokubuyisela ikhetha kanjani amabhande?
Iqoqa isifiso sakho kuxabiso eliphakathi lezinhlamvu ezihambayo ezikwazi ukuveza, bese ikhetha umphinda-phindo ukuze ufunde ulinganise - amamibala afanayo ongazifunda ngaphandle kwe-resistor engokoqobo yale ntengo.
Yini ushintsho phakathi kwe-4-, 5- ne-6-band resistors?
A 4-band resistor has two digit bands; a 5-band engeza i-digit yesithathu for tighter tolerance like ±1%; futhi a 6-band engeza iband ekugcineni izinga lokushisa-coefficient ebonisa ukuthi inani drifts ngamazinga. Amabhande amaningi ngokuvamile kusho ingxenye engcono.
Yisiphi isiphelo se-resistor engingafunda kuqala?
Qala kusuka kubhande elincane kakhulu elingasemuva bese ufunda ukuya kubhande lokubekezela, elivame ukuba ngugolide noma igolide elinciphisa ukuhlukaniswa kokunye. Uma ugolide noma igolide lihlala engxenyeni eyodwa, lokhu kuyibhande lokubekezela, ngakho funde kusuka engxenyeni ephikisanayo.
Yini okusho amabhande egolide negolide?
Kulesi simo multiplier igolide isho × 0.1 futhi igolide isho × 0.01, ukunika sub-ohm amaxabiso. Kulesi simo ukubekezela igolide isho ± 5% futhi igolide isho ± 10% - ezimbili ezivame kakhulu ubusuku bonke ukubekezela.
Kungani ayikho inqwaba yami elinganiselwe ngokuqinile ilingana ikhodi?
Amabhande anikeza inani elibizwa ngokuthi lihlobene nefasitela lokubekezela. I-±5% 1 kΩ resistor ingalinganisela ngokusemthethweni noma kuphi kusuka ku-950 Ω kuya ku-1,050 Ω, futhi izinga lokushisa nobudala kungashintsha ngaphezu, ngakho-ke ukungqubuzana okuncane ku-multimeter kujwayelekile ngokuphelele.
API — sebenzisa le calculator kusuka kukhodi
