2. Electric potential and capacitance — Physics STD 12 Science — Question

CBSE BoardEnglish MediumSTD 12 SciencePhysics2. Electric potential and capacitance1 Mark
MCQ
While a capacitor remains connected to a battery and dielectric slab is applied between the plates, then
  • A
    Potential difference between the plates is changed
  • ✓
    Charge flows from the battery to the capacitor
  • C
    Electric field between the plates increases
  • D
    Energy store in the capacitor decreases
✓

Answer

Correct option: B.
Charge flows from the battery to the capacitor
b
(b) By inserting the dielectric slab. Capacitance (i.e. ability to hold the charge) increases. In the presence of battery more charge is supplied from battery.
