Three identical lamps are connected to a battery as shown in the diagram. Each lamp operates at normal brightness and the ammeter (of negligible resistance) registers a steady current.
The filament of the lamp W breaks. What will happen to the ammeter reading and to the brightness of the remaining lamps?
Ammeter reading-----Lamp brightness
AIncreases---Decreases
BDecreases---Remains unchanged
CRemains unchanged---Remains unchanged
DBecomes zero---Becomes zero
