True or False?
A dielectric slab is slowly inserted between the plates ofaparallel-plate capacitor, while the potential differencebetweenthe plates is held constant by a battery. As the slab isbeinginserted, the capacitance, the potential difference betweentheplates, and the charge on the positive plate all increase.
A parallel-plate capacitor, with air dielectric, is charged byabattery, after which the battery is disconnected. A slab ofglassdielectric is then slowly inserted between the plates. As itisbeing inserted, electric force attracts the glass into thespacebetween the capacitor.
Two capacitors are identical except that one is filled with airandthe other with oil. Both capacitors carry the same charge.Theratio of the electricfieldsEair/Eoiliszero.
A parallel-plate capacitor, with air dielectric, is charged byabattery, after which the battery is disconnected. A slab ofglassdielectric is then slowly inserted between the plates. As itisbeing inserted, the magnitude of the charge on eachplateincreases.
A parallel-plate capacitor, with air dielectric, is charged byabattery, after which the battery is disconnected. A slab ofglassdielectric is then slowly inserted between the plates. As itisbeing inserted, the potential difference between theplatesdecreases.
