Q. 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
B) Charge flows from the battery to the capacitor
C) Electric field between the plates increases
D) Energy store in the capacitor decreases
Explanation
(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
