Zaryadlagandan keyin oraliqni qisqartirish
As shown, a parallel-plate capacitor is connected to an 8 V source, fully charged, then disconnected, and the plate separation d is reduced by half. What is the potential difference between the plates?

Rasmda ko‘rsatilganidek, yassi kondensator 8 V li manbaga ulanib, to‘liq zaryadlangan, so‘ng uzib qo‘yilgan va qoplamalar orasidagi d masofa ikki marta kamaytirilgan. Qoplamalar orasidagi potensiallar farqi nimaga teng?
