Misali ya Nau'ukan Rikitar Daɗi?
Na wani Conductor Resistance Test?
Ta’rifin Conductor Resistance Test
An yanayi tushen DC resistance na kawo kofin ko aluminum conductors don neman yadda ake da suka shiga current flow.
Muhimmin Resistance
Mafi yawan resistance a cikin conductor ya ba mafi yawan current flow, wanda yana da muhimmanci a fadin hanyar power transmission.
Equipment na Test
An yanayi Kelvin Double Bridge ko Wheatstone Bridge don neman resistance da zan iya amfani da shi.
Tsarin Testing
Sambata specimen zuwa bridge na resistance measuring kuma ambaci cewa an samun abubuwan da za su iya haɗa da contact resistance.
Nemo resistance kuma tattara temperature.
Resistance da aka nemo an sa ta zuwa standard temperature da length.
Calculation
Observed Resistance a fili mai temperature,
R t = Observed Resistance
K = Temperature correction factor
L = Length of specimen in m.
Kalmar
Abubuwan da aka nemo sun nuna idan conductor ya tabbatar da ma'adiniton resistance, wanda yake da muhimmanci don inganta gaskiya a electrical power cables.
