Mubvunzo uyu une chekuita nemutemo waKirchhoff . Maitiro ekugadzirisa dambudziko iri:
Kutanga , sarudza kwakananga magetsi. Unogona kusarudza kuti magetsi ari kupi kana kuti akananga kupi nenzira yewachi.
Chechipiri , kana magetsi achipfuura nepakati pe resistor (R) paine mukana wekuderera zvekuti V = IR yasainwa negative. Chechitatu , kana magetsi achichinja kubva pavoltage yakaderera kuenda pavoltage yakakwira (- kusvika +) ipapo sosi ye emf (E) yasainwa negative nekuda kwekuchaja kwesimba pasource ye emf. Kana magetsi achichinja kubva pavoltage yakakwira kuenda pavoltage yakaderera (+ kusvika -) saka sosi ye emf (E) yasainwa negative nekuda kwekubuda kwesimba pasource ye emf.
