Resistance hlau yog ib qho tseem ceeb ntawm ntau yam khoom siv hluav taws xob thiab hluav taws xob thiab ua ntau yam haujlwm tseem ceeb rau lawv txoj haujlwm. Lub luag haujlwm tseem ceeb ntawm cov hlau tsis kam yog los thaiv qhov ntws ntawm cov hluav taws xob tam sim no, yog li hloov hluav taws xob hluav taws xob mus rau hauv tshav kub. Cov cuab yeej no ua rau cov hlau tsis muaj zog hauv cov ntawv thov xws li cov khoom cua sov, kev tiv thaiv hluav taws xob, thiab kev tswj qhov kub thiab txias.
Ib qho ntawm feem ntau siv raukuj hlauyog nyob rau hauv cov khoom cua sov, uas yog siv los ua kom muaj cua sov rau ntau yam kev siv. Los ntawm lub qhov cub hluav taws xob thiab qhov cub mus rau qhov cub thiab qhov chaw cua sov, cov hlau tsis kam ua lub luag haujlwm tseem ceeb hauv kev hloov hluav taws xob rau hauv hluav taws xob. Resistance hlau muaj peev xwm tiv taus qhov kub thiab txias thiab nws cov conductivity zoo heev ua rau nws zoo tagnrho rau kev siv cua sov.
Ntxiv rau lawv lub luag haujlwm hauv cov khoom cua sov, cov xov hlau tiv thaiv kuj tseem siv rau hauv cov khoom siv tiv thaiv hluav taws xob xws li fuses thiab Circuit Court breakers. Thaum cov tam sim no dhau mus rau hauv ib lub voj voog, cov xaim hluav taws xob ntawm lub fuse ua kom sov thiab melts, tawg lub Circuit Court thiab tiv thaiv kev puas tsuaj rau cov khoom siv txuas. Ib yam li ntawd, hauv Circuit Court breakers, cov xaim hluav taws xob tiv thaiv yog tsim los rau kev mus ncig thiab rhuav tshem lub voj voog thaum muaj kev sib tsoo, yog li tiv thaiv cov hluav taws xob los ntawm kev phom sij.
Tsis tas li ntawd, cov hlau tsis kam yog ib qho tseem ceeb ntawm kev tswj qhov kub thiab txias rau cov khoom siv xws li thermistor thiab thermocouples. Thermistors yog qhov ntsuas kub-rhiab heev uas siv cov xaim hluav taws xob los ntsuas thiab tswj qhov kub thiab txias hauv cov ntawv thov xws li kev tswj hwm lub cav tsheb mus rau cov khoom siv kho mob. Ib yam li ntawd, cov thermocouples siv cov xaim hluav taws xob los ntsuas qhov sib txawv ntawm qhov kub thiab txias thiab hloov mus rau hauv cov teeb liab hluav taws xob, uas ua rau lawv tseem ceeb rau kev ntsuas kub thiab tswj hauv cov txheej txheem kev lag luam thiab kev tshawb fawb tshawb fawb.
Lub versatility ntawmtiv thaiv kab mobtxuas mus rau lawv siv nyob rau hauv cov khoom siv hluav taws xob xws li cov resistors, uas yog siv los tswj cov tam sim no hauv Circuit Court. Los ntawm kev muab cov qib tshwj xeeb ntawm kev tiv thaiv, cov xaim hluav taws xob tuaj yeem tswj tau cov yam ntxwv hluav taws xob ntawm lub voj voog, ua rau lawv yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob thiab cov tshuab.
Tsis tas li ntawd, cov kab hluav taws xob tiv thaiv tau siv rau hauv cov chaw tshwj xeeb xws li aerospace thiab kev tiv thaiv, qhov twg lawv txoj kev ntseeg siab thiab kev ua tau zoo nyob rau hauv huab cua yog qhov tseem ceeb. Hauv kev siv aerospace, cov xov hlau tiv thaiv tau siv rau hauv cov cua sov, de-icing systems thiab thermal tswj kev daws teeb meem rau cov khoom siv dav hlau. Lawv muaj peev xwm tiv taus qhov kub thiab txias ib puag ncig ua rau lawv zoo tagnrho rau kev ua kom muaj kev nyab xeeb thiab ua haujlwm tau zoo ntawm cov tshuab aerospace.
Qhov tseem ceeb ntawm kev tiv thaiv hlau nyob rau hauv ntau yam kev lag luam thiab cov ntawv thov qhia nws qhov tseem ceeb hauv cov cuab yeej siv niaj hnub no. Nws muaj peev xwm hloov hluav taws xob hluav taws xob mus rau hauv tshav kub, tswj tam sim no thiab pab tswj qhov kub thiab txias ua rau nws yog ib qho tseem ceeb ntawm cov cua sov, hluav taws xob thiab hluav taws xob. Raws li kev siv thev naus laus zis txuas ntxiv mus, qhov kev thov rau cov kab hluav taws xob ua haujlwm siab nrog kev txhim kho cov yam ntxwv tseem yuav loj hlob ntxiv, ntxiv dag zog rau lawv lub luag haujlwm hauv cov cuab yeej thiab cov tshuab uas muaj zog rau lub ntiaj teb niaj hnub no.
