Just as Isaac Newton''s first Law of Motion ("an object in motion tends to stay in motion; an object at rest tends to stay at rest") describes the tendency of a mass to oppose changes in velocity, we can state a capacitor''s tendency to oppose changes in voltage as such: "A charged capacitor tends to stay charged; a discharged capacitor tends to ...
Charge–discharge properties of an La-modified Pb(Zr,Sn,Ti)O3 (PLZST) antiferroelectric (AFE) ceramics capacitor were investigated by directly measuring its hysteresis loops and pulse discharge current–time curves under different electric fields. Large increments in polarization and discharge current were observed when the electric field increases from …
