Flashlight: electrical energy -> radiant energy
Battery: chemical energy -> electrical energy
Toaster: electrical energy -> heat energy
Motor: electrical energy -> kinetic energy
The conversion is from chemical energy to electricity to light energy.
The conversion is from chemical energy to electricity to light energy.
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 stored chemical energy in the battery is transfered into light energy and heat.
The popular energy of flashlight are Rechargeable Li-on battery, Alkaline battery.
From electrical energy to heat energy
The energy transfer in a toaster is electrical to heat (and light if the elements are glowing) and Conversion is electric to radiation.
Battery electric energy is converted to light energy of flashlight.
