It's the other way around, the battery powers the flashlight.
There's no set answer to that. It depends on the capacity of the battery and the power consumption of the flaslight.
The energy conversion in a battery powered flashlight comes from the battery itself. Batteries use metal electrodes set into a chemical paste to store electricity; as the electrode oxidizes it releases electrons.
The conversion is from chemical energy to electricity to light energy.
The conversion is from chemical energy to electricity to light energy.
The popular energy of flashlight are Rechargeable Li-on battery, Alkaline battery.
Battery electric energy is converted to light energy of flashlight.
Potential energy
Chemical energy is changed to electrical energy. Electrical energy heats the filament of the bulb, changing to heat. The hot filament glows, giving off light
potential energy
A battery is the electrochemical cell is used as an energy source in a flashlight.
flashlight: the battery in the flashlight transforms it's chemical stored Energy into electrical Energy which is then transformed into radiant energy because of the light the flashlight gives off.
The flashlight can not be turned on as it no power now.
