Amaxabiso Resistor nesikhundla yazo

Resistor - wesiphaluka into, nto leyo isebenza ukunciphisa yangoku ngazo. Kwakhona, resistors zisetyenziswa ukunciphisa uxinzelelo kwezinye iindawo kunye nokwahlukana kwi candelo current yayo. Kwiisekethe zombane resistors zibonakaliswe yi iingxande encinane iperi izikhonkwane (omnye kwi zalo ezimbili). resistors phesheya zimelwe ngelayini eyaphukileyo.

Resistors ezikulu iparameters ezintathu:

1. ukumelana Standard (amaxabiso resistor).
2. Nokunyamezelana.
3. Power ukusasaza.

Amaxabiso Resistor - ixabiso nokumelana yabo ngegama, oko kukuthi, ixabiso kucacise umenzi. Wesiqhelo uxhathiso lulinganiselwa ngo ohms. Resistors zisetyenziswa phantse zonke amashishini, ukuba izixhobo kancinane zombane. Oku kukhokelela kuluhlu enkulu lwamaxabiso ukuxhathisa. Nangona kunjalo, kukho amaxabiso resistor, akhona jikelele.

Azenzi resistor nge njengezifanelekileyo ezithile ngqo akukho nzima kakhulu, ngoko sebenzisa eli xabiso njenge nokunyamezelana. Umzekelo, ukuba ukumelana elikhankanyiweyo wesiqhelo elingana ohms 10, enyanisweni bekuya kuba malunga 10.1 9,98- ohms. Le nto ibizwa ngokuba nokumelana impazamo kunokwenzeka kwaye zilinganiswe njengepesenti.

Power ukusasaza - ngomnye weyona miba ibaluleke kakhulu ekumiseleni resistor. Cacisa intsingiselo yenani elinikiweyo. A resistor nge apho sombane ngoku lusoloko shushu ngako. Ukutshisa kuxhomekeke amandla yangoku. resistor ngalinye umda ethile lobushushu ngaphaya apho overheats kwaye iphelelwe. Ukusasaza - kunenzuzo ze ngamandla electric current, apho resistor liya kuzitshisa ngomlilo. Kanye amaxabiso resistors, amandla ukusasaza - yinto rhoqo ngamnye kubo. Oku kuboniswa umenzi. On eesekethe zombane dissipated amandla resistor kufuneka zicaciswe. Kutyunjwa yayo kusetyenziswa imigca liyayithanda, othe tye kunye nkqo. Ukususela umfanekiso kwi resistor imigca icon ezi zizifundo ezizodwa ebonisa amaxabiso ezahlukeneyo amandla. Amaxabiso eqhelekileyo kwizikim ezincinane uluhlu phakathi watt 1/8 kunye watts ezintlanu. Power ukusasaza nayiphi na resistor na kubalwa ukusuka umthetho Ohm ukuze subcircuit. Ukuchaza oko, kufuneka wazi yangoku kwisekethe kunye ixabiso eliyimali le resistor.

Zonke Ukulinganiswa ukumelana standardised. Oko kukuthi, kukho ezinye amaxabiso standard resistor. Le migaqo ke, nayo ngokwamaqela kwimigca ebusweni amaxabiso resistors. Kuba abanjalo series DC Guest 6: E6, E12, E24, E48, E96, E192.

Ngokuba izinto ngoku zisetyenziswa manqaphanqapha zeeteksi E6 kunye E3. Amanani amagama lemiqolo amele inani amanqaku kunokwenzeka kolu ngcelele. Umzekelo, inani yamahlelo E6 ibandakanya kuphela kunokwenzeka ilandelayo uxhathiso: 1.0; 1.5; 2.2; 3.3; 4.7; 6.8.
