Question

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. Change flows from the battery to the capacitor
C. Electric field between the plates increases
D. Energy store in the capacitor decreases

Answer 1

Correct Answer - B
By inserting the dielectric slab. Capacitance (i.e., ability to hold the change) increases. In the presence of battery more change is supplied from battery.
