Fomura Yekudzivirira Magetsi

Muchinyorwa pamusoro pemutemo weOhm, fomura yakawanikwa inotaura hukama huripo pakati pemagetsi emagetsi (V), magetsi emagetsi (I) uye kuramba kwemagetsi (R). Pamasvomhu, inoratidzwa kuburikidza ne equation:

Iyi equation inoratidza kuti resistance yemagetsi (R) inoenderana zvakananga nevoltage (V) uye inoenderana necurrent (I). Kana voltage yakakura, resistance inowedzera. Kusiyana neizvi, kana current yakakura, resistance inowedzerawo. Iyi equation inotsanangura mutemo weOhm chete kana resistance (R) iri constant. Kana resistance isiri constant, iyi equation haitsananguri mutemo weOhm asi inotsanangura resistance yeconductor.

Akabvunzwa: Kuchinja kwesimba remagetsi (ΔEP)
Mhinduro:
ΔEP = q V = (-1,60 x 10^-19 C(12 V) = -19,2 x 10^-19 Joule
Chiratidzo chekusateerera chinoreva simba remagetsi inoderera. Kana iri pedyo neplate ine negative charge, simba remagetsi remaerekitironi rinosvika pakakwirira. Mushure mekusvika pedyo neplate ine positive charge, simba remagetsi remaerekitironi rinosvika pakaderera.
