alleryIn a capacitor circuit, when a dielectric is inserted while voltage is HELD CONSTANT by battery, the CHARGE on capacitor:
AStays same
BDecreases
CIncreases
DBecomes zero
Answer & Solution
Correct answer: C. Increases
With battery connected (V constant), inserting dielectric increases C, hence Q = CV increases (Q grows).
Extra charge flows from battery to capacitor.
If battery is disconnected first, C increases but Q stays same → V drops.
