Lub luag haujlwm ntawm resistors
Cov thev naus laus zis feem ntau siv cov khoom thauj kom nqus tau cov hluav taws xob tsis tsim nyob rau lub sijhawm siv cov khoom, lossis ua lub luag haujlwm hauv kev tiv thaiv thiab nres. Tsis tas li ntawd, rau siab-ua qhov kev tiv thaiv, nws tsis raug tso cai kom muaj qhov cuam tshuam loj hauv cov khoom, uas yuav tsum xaiv cov khoom siv zoo thiab cov txheej txheem siab.
