I-Calculator yekhodi lombala we-Resistor
Ukufaka ikhodi 4/5/6-band resistor imibala elinganayo — noma ushintshe inani libe yi-bands.
Iziphetho zivuselelwa uma ubhala.
Malunga nale khadi
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; 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.Switch to reverse (encode) mode to go the other way: type a target resistance pattern and the tool rounds it to the nearest value
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 adds a third digit for tighter tolerances like ±1%; and a 6-band adds a final temperature-coefficient band showing how much the value drifts per degree. More bands generally means a more precise part.
Yisiphi isiphelo se-resistor engingafunda kuqala?
Qala kusuka kubhande elincane kakhulu elingasemuva bese ufunda ukuya kubhande lokubekezela, okungukuthi, igolide noma isiliva futhi lihlukaniswe kancane kusuka ekugcineni. Uma igolide noma isiliva 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 lokumelana. I-±5% 1 kΩ resistor ingalinganiselwa ngokusemthethweni nakweyiphi na indawo kusuka ku-950 Ω kuya ku-1,050 Ω, futhi izinga lokushisa nobudala kungashintsha ngaphezu, ngakho-ke ukungqubuzana okuncane ku-multimeter kujwayelekile ngokuphelele.
