Kunzwisisa Simba reMagetsi
Simba, sezvakadzidzwa muchikamu chebasa nesimba , rinotsanangurwa sebasa rinoitwa panguva yakatarwa. Basa inzira yekushandura simba, saka simba rinogona kunzwisiswa sekuchinja kwesimba panguva yakatarwa.
Simba remagetsi kuchinja kwesimba remagetsi panguva yakatarwa. Kukurukurirana pamusoro pesimba remagetsi kunotsanangura kuti shanduko musimba remagetsi rinoitika kana chaji yemagetsi inopfuura nemusiyano wesimba remagetsi.
Fomura
Pamasvomhu, shanduko musimba remagetsi (ΔEP) inoenderana nechaji (Q) uye voltage yemagetsi (V), inoratidzwa kuburikidza ne equation ΔEP = Q V. Simba shanduko musimba remagetsi panguva yakatarwa, inoratidzwa nemasvomhu kuburikidza ne equation 1 :
Chaja yemagetsi inoyerera panguva yakati imagetsi , anoratidzwa nemasvomhu kuburikidza ne equation I = Q/t. Equation 1 inogona kuchinjwa kuita equation 2 :
Zvichibva pamatanho maviri aya, zvinogona kugumiswa kuti shanduko musimba remagetsi panguva yakatarwa inoitika kana magetsi emagetsi adarika nemusiyano wesimba remagetsi. Simba rinoenderana nemagetsi emagetsi uye simba remagetsi, saka, kana magetsi emagetsi uye/kana simba remagetsi rikawedzera, simba racho rinowedzerawo.
Kana magetsi emagetsi akayerera nepakati pe resistor, simba racho rinoverengerwa uchishandisa equation 3 kana equation 4.
Chikamu
Zvichibva pa equation 1 , International System unit of energy ndiyo Joule uye International System unit of time ndiyo yechipiri, saka unit of power ndiyo Joule/second, yakapfupikiswa seJ/s. Joule/second inonziwo Watt. 1 Watt = 1 Joule/second.
Zvichibva pa equation 2 , unit ye electric potential iVolt uye unit ye electric current iAmpere saka unit ye electric power iVolt Ampere, yakapfupikiswa seVA.
