Three similar light bulbs are connected to a constant voltage d.c supply as shown in the diagram. Each
bulb operates at normal brightness and the ammeter
(of negligible resistance) registers a steady current.
The filament of one of the bulbs breaks. What happens to the ammeter reading and to the brightness of the remaining bulbs?
|Ammeter reading||Bulb brightness|
The correct answer should be D because when current decreases,brightness also decreases
