How does the amount of energy in the batteries of a flashlight compare to the total amount of energy given off by the flashlight as light and heat?
For a normal battery,for example,AA,AAA,CR123A,CR2 it can just work alittle time and not steady. But for charging batteries,it is steady and can be used fora long time,for a normal 18650 battery,with 70 LM, it can be used for 2-3 hours the LED flashlight is excellent,here is an experience i can share with you: It was a night,when i come bace to my home late,but that day was very special,because it was very dark everything not as usual,then when i went to a shop,i was told our power cut.How worried i was because i can do nothing.Hardly have i reached my house i found it was very bright.My housemate are using her LED flashlight,how happy i was,still i can do everything as usual.She told me she bought from her friend 8 years ago who work in a manufacturer and make LED fllashlith,he said the LED recharging flashlight using special ulria bright white LED,LED light source is the best light source in the world,it is environment protect,long use time (about 3 times)than any other light(incandescente lamp,mecury lamp).and power save,safe and solid performance,realy excellent.And then it was working as the first ,high bright.Sometimes she took it to travel and Camping, climbing, fishing, and other outdoor sports and so on.It just recharge for 4 hours and can charge more than 2 hours.He just need to recharge indoor and then took it is ok. I was so attracted by this LED flashlight, so then i bought one too.Excellent!!!
What else can I help you with?
How does the amount of energy in batteries in a flashlight compare to the total amount of energy given off byt the flashlight as light and heat?
All of the energy in the battery, or most of it, is eventually given off as heat and light.
How does the amount of energy in the batteries compare to the total amount of light given off by the flashlight?
The amount of energy stored in the batteries is typically higher than the total amount of light output by the flashlight, as some energy is lost as heat during the conversion process. The efficiency of the flashlight will determine how much of the stored energy is actually converted into light.
Does a flashlight burn more energy?
No, a flashlight does not "burn" energy. It consumes energy from its batteries or power source to produce light. The amount of energy consumed depends on the type of flashlight and its brightness settings.
How does the amount of energy in batteries in a flashlight compare to the total amount of energy given off by the flashlight as light and heat?
There is more energy in the battery than that given off as light and heat for two reasons. 1) Some energy is lost due to resistance in the battery. As current flows, energy is lost to heating of the battery due to this internal resistance. 2) As the battery operates, the voltage falls until it is too low to heat the bulb to incandescence. Yet energy remains in the battery, but this last energy is at too low a voltage to be useful.
Where does energy come from a flashlight?
In a flashlight, energy comes from the batteries. The batteries provide electrical energy to power the light bulb or LED in the flashlight, producing light as a result.

What is another kind of energy that a flashlight gets?
A flashlight can also get energy from batteries or rechargeable batteries to power the light source.
What are the energy transformations are involved using a flashlight?
In a flashlight, electrical energy from the battery is transformed into light energy and a small amount of heat energy in the bulb. The batteries store chemical energy that is converted into electrical energy, which then powers the light-producing mechanism in the flashlight.

What energy transformation is ins flashlight?
A flashlight transforms electrical energy from batteries into light energy and heat energy.
Stored energy in a flashlight and batteries becomes light energy when the flashlight is turned on?
Yes, when a flashlight is turned on, the stored chemical energy in the batteries is converted into electrical energy, which then gets converted into light energy by the bulb. The light energy is what we perceive as the beam of light emitted from the flashlight.
What form of energy is stored in a flashlight?
Chemical energy is stored in a flashlight in the form of batteries. When the flashlight is turned on, the chemical energy is converted into electrical energy, which powers the light bulb.
