Tsanangudzo yesimba remagetsi
Simba rinodzidzwa mubasa uye Simba rinotsanangurwa sebasa rinoitwa panguva yakatarwa. Basa inzira yekuchinja simba kuitira kuti simba rinzwisiswe sekuchinja kwesimba kunoitika panguva yakatarwa.
Simba remagetsi kuchinja kwesimba remagetsi panguva yakatarwa. Mukuongorora simba remagetsi, zvinotsanangurwa kuti kuchinja kwesimba remagetsi kunoitika kana chaji yemagetsi inopfuura nepakati penzvimbo. kugona kwemagetsi mutsauko.
Equation yesimba remagetsi
Pamasvomhu, shanduko musimba remagetsi (ΔEP) inoenderana nechaji (Q) uye voltage yemagetsi (V), inoratidzwa ne equation ΔEP = Q V.
Simba shanduko yesimba remagetsi rinogoneka panguva yakatarwa, rinoratidzwa nemasvomhu kuburikidza ne equation 1:
Chaja yemagetsi inoyerera panguva yakati inguva yemagetsi, inoratidzwa 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 remagetsi rinoenderana nesimba resimba remagetsi nesimba remagetsi, saka kana magetsi emagetsi nesimba remagetsi zvikawedzera, simba remagetsi rinowedzerawo.
Kana magetsi emagetsi akayerera nepakati pe resistor ine resistance yemagetsi inogara iripo, simba remagetsi rinogona kuverengerwa uchishandisa equation 3 kana equation 4.
Chikamu chesimba remagetsi
Zvichibva pa equation 1, International System unit of Energy iJoule uye International System unit yenguva ndiyo yechipiri saka unit yemagetsi iJoule/yechipiri, muchidimbu J/s. Joule/yechipiri inonziwo Watt. 1 Watt = 1 Joule/yechipiri.
Zvichibva pa equation 2, unit ye electric potential iVolt uye unit ye electric current iAmpere saka unit ye electric power iVolt Ampere, yakapfupikiswa VA.
