what is a conclusion for a battery powered light bulb
The battery chemically stores electricity so when you 'switch on' the light then electricity flows from the battery to the bulb. The bulb the heats up to glow white and the reflector shines the light out of the battery powered light
Cowen
You bet! It's called a flashlight, too. Some camping lamps use fluorescent bulbs and batteries to emit about the same amount of light.
A battery-powered torch converts chemical energy stored in the battery into electrical energy, which is then converted into light energy when the circuit is completed and the bulb is illuminated.
In a battery-powered flashlight, chemical energy stored in the battery is converted into electrical energy when the battery generates a current. The electrical energy is then converted into light energy when the current passes through the light bulb or LED, producing light.
You can buy a battery powered light at the bicycle shop.
Save your cell battery
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.
1. battery is bad 2. charger is bad 3. charger outlet is powered off by light switch
Reasonobaly low. maximum 7 for Ds. just fiddle around with differend bulbs and batteries unless the battery is lead-acid
