Bulb in B lights brighter than Bulb in A
The more the batteries, the brighter the bulb.
A battery is the source of electrical energy in a circuit so the more the battery, the more the electrical energy is converted to light energy.
The bulb may fuse (filament in the bulb will break/melt)
toys (eg remote control car) and torchlight
