Abaningi Izingxenye ze-elekthronikhi banamagama ezincazelo noma izinhlelo zokuzikhomba. Ngokwesibonelo, Amakhodi ombala we-Resistor, okuzonquma ukumelana nama-ohms abakwazi ukuwakhulisa, kanye nokubekezelelana. Kubalulekile ukwazi lawa makhodi ukwazi ngohlobo lokumelana onalo phambi kwakho lapho ungenalo olunye usizo lokwazi ukubaluleka kwalo, njenge-multimeter.
Kulesi siqondisi esisheshayo ungakwazi funda ukwambula amakhodi kwama-resistors ukuthola inani kuma-ohms nokubekezelelana kwawo, kokubili kuma-resistors ajwayelekile nakwezinye izinhlobo zama-resistors ...
Amakhodi wombala wokumelana
Ngokuya ngohlobo lokumelana, amakhodi ombala zingahluka. Ukuze ukwazi ukucacisa amanani kuma-ohms nokubekezelelana kufanele wazi lawa amathebula wamakhodi ombala wama-resistors.
Ama-4 nama-5 amabhendi
Okokuvikela okuvamile kwe- Ama-4 nama-5 amabhendi, ungasebenzisa leli thebula ukuthola inani lalo:
Njengoba ukwazi ukubona, ngenhla nangaphansi unesibonelo sokubala ukuze ubone ukusebenza kwalolu hlobo lwamatafula. Isibonelo, i-resistor 5-band enemibala ensundu, emnyama, emnyama, ebomvu, negolide, kungasho ukuthi unayo I-10 kΩ nokubekezelelana ±5%, okungukuthi, lingahluka lelo nani ngaphezulu noma ngaphansi kuka-5%, ngoba alinembile.
Ngakho-ke, inqubo ilula, vele ukhombe ukuthi inemibala emi-4 noma emi-5, bese ubheka umbala ngamunye ngokulandelana kwetafula. Kulesi sibonelo kungaba:
- UBrown: umbala onsundu esiqeshini sokuqala usho ukuthi 1. Kuzoba idijithi yokuqala yenombolo ezophindaphindwa ngophindaphindayo.
- Negro: okumnyama emgqeni wesibili ngu-0. Kuyinombolo yesibili.
- Negro: umnyama emgqeni wesithathu ngu-0.Idijithi yesithathu.
- I-Rojo: okubomvu emgqeni wesine kungukuphindaphinda, okuzophakanyiswa ku-10 kudijithi ehambelana nalowo mbala. Kulokhu x 102.
- UDorado: ukubekezelelana kwe- ±I-5%.
Ngakho-ke, 100 x 102 = 10.000, okungukuthi, 10k.
Ezinye iziphikisi
Njengoba ukwazi ukubona, amakhodi ombala wama-resistors wemivimbo engu-4 no-5 ngeke avumeleke amanye ama-resistor. Isibonelo, ukukhuphuka komhlaba, ama-potentiometers (okuguquguqukayo), njll.
Izinsiza
Ngaphezu kokukwazi ukuba namatafula wangaphambilini wamakhodi ombala wama-resistors, kufanele wazi ukuthi akhona Ama-otros recursos onawo ukuze ukwazi ukuxhumana nabo ngokunethezeka kusuka noma ukuphi. Isibonelo, unamakhasi athile e-web wokubala noma ezinye izinhlelo zokusebenza zamadivayisi eselula kutholakale kalula:
- I-DigiKey: web nge-calculator yamanani ngokuya ngekhodi yokumelana. Ngendlela, uma ufuna leli gama ku-Google Play noma ku-App Store, uzobona ukuthi nalo linohlelo lokusebenza lokulisebenzisa ngokunethezeka.
- ElectroDoc: Uhlelo lokusebenza lwe-Android olunamakhodi ombala we-resistors nolunye ulwazi oluningi mayelana namafomula, izibalo, amasekethe, izingxenye, njll.
- Resistor Umbala Wekhodi Calculator: uhlelo lokusebenza olusebenziseka kalula lokubala amanani we-resistor ngemibala yawo.
