Qhov hluav taws xob tsis zoo, ib txwm Cov cim tsis zoo hauv Faraday txoj cai (Lenz txoj cai) tsis txhais hais tias EMF (lossis tam sim no) ib txwm taw qhia hauv qee qhov "tsis zoo". Nws txhais tau hais tias tam sim no ib txwm ntws mus rau hauv txoj hauv kev los tawm tsam qhov kev hloov pauv hauv flux, uas tau piav qhia zoo hauv qhov video clip.
Puas yog emf tuaj yeem tsis zoo?
Yes, peb tuaj yeem muaj qhov tsis zoo. Cov cim tsis zoo txhais tau hais tias lub zog hluav taws xob uas raug ntxias yuav raug ntxias kom tawm tsam qhov ua rau. Piv txwv tias emf yog induced los ntawm ib tug sib nqus teb nyob rau hauv lub -z kev taw qhia, lub emf yuav induced los tsim ib tug magnetic teb nyob rau hauv lub +z kev taw qhia.
Yuav ua li cas thaum emf tsis zoo?
Lub zog hluav taws xob (EMF) yog qhov sib txawv siab tshaj plaws ntawm ob lub electrodes ntawm galvanic lossis voltaic cell. Yog tias lub peev xwm ntawm tes tsis zoo, cov tshuaj tiv thaiv rov qab. Nyob rau hauv cov ntaub ntawv no, lub electrode ntawm galvanic cell yuav tsum tau sau nyob rau hauv ib tug reversed kev txiav txim.
Puas emf yuav tsum muaj qhov zoo?
Qhov siab tshaj qhov sib txawv uas tuaj yeem ntsuas tau rau ib lub xovtooj hu ua electromotive force, abbreviated emf thiab sawv cev los ntawm lub cim E. Los ntawm lub rooj sib tham, thaum lub xovtooj tau sau ua lus luv luv, nws emf muab tus nqi zoo yog tias cov tshuaj tiv thaiv ntawm tes yog tus kheej
Puas yog EMF rov qab zoo lossis tsis zoo?
Thaum koj qhib qhov hloov pauv, tsis muaj qhov siv hluav taws xob, thiab txhua yam uas muaj nyob thoob plaws lub cev muaj zog yog EMF rov qab. Lub galvanometer nyeem yog li mus negative, thiab nws nce siab thaum lub cev muaj zog qeeb, mus rau xoom thaum lub cev muaj zog nres. Rov qab EMF tuaj yeem yog qhov tseem ceeb rau kev ua haujlwm ntawm lub tshuab hluav taws xob.
