Kuchuluka komwe kwapezeka ndi mayunitsi ake apadziko lonse lapansi akuwonetsedwa ndi nambala……
Anakonza
(1) Kuchuluka: kuchuluka komwe kwachokera
(2) Mphamvu yamagetsi : kuchuluka kwa maziko
(3) Mphamvu ya kuwala: kuchuluka kwa maziko
(4) Voltage yamagetsi : kuchuluka komwe kumachokera
(5) Kupanikizika : kuchuluka komwe kumachokera
Kuchuluka komwe kwapezeka ndi mayunitsi awo apadziko lonse lapansi akuwonetsedwa ndi manambala (1), (4), ndi (5)
