2. Voltage ƙarfin lantarki daidai g33:

g33 = UP / P ƙara P irin wannan matsin lamba a kan kwakwalwan kwamfuta. Samar da irin wannan ƙarfin lantarki mai girma a kan kwakwalwan kwamfuta, g33 ya fi girma, ƙarfin karɓar ya fi girma.

3. Dielectric daidaitacce e:

e = Ct / A [C-Capacitive, t-polar panel nesa (kwakwalwan kwamfuta kauri), A-polar panel yanki (kwakwalwan kwamfuta yanki)];

C karami → e karami → caji, watsa lokaci gajeren. Babban mita.

4. Electromechanical coupling coefficient K:

Yana nuna ingancin canzawa tsakanin makamashin inji (sauti) da makamashin lantarki.

Don ingantaccen sakamakon lantarki: K = karfin lantarki da aka canza / karfin inji da aka shigar.

Don reverse voltage lantarki tasiri: K = canza inji makamashi / shigar da lantarki makamashi.
