Flashlight: electrical energy -> radiant energy
Battery: chemical energy -> electrical energy
Toaster: electrical energy -> heat energy
Motor: electrical energy -> kinetic energy
Energy conversion takes place in a flashlight when the electrical energy from the battery is converted into light energy and heat energy through the process of powering the light bulb or LED. This conversion occurs instantly when the circuit is completed and the flashlight is turned on.
The conversion is from chemical energy to electricity to light energy.
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.
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 popular energy of flashlight are Rechargeable Li-on battery, Alkaline battery.
The energy transfer in a toaster is electrical to heat (and light if the elements are glowing) and Conversion is electric to radiation.
When you turn on a flashlight, electrical energy from the battery is converted into light energy and thermal energy. The electrical energy powers the bulb, causing it to emit light, while some of the energy is also lost in the form of heat.

In a flashlight, electrical energy from the battery is transformed into light energy and some heat energy by the light bulb. This process involves the conversion of electrical energy into electromagnetic radiation in the form of visible light.
Energy in a flashlight changes from stored chemical energy in the battery to electrical energy when the battery powers the light bulb, which then converts electrical energy into light and heat energy.
When a battery-powered flashlight is switched on, chemical energy stored in the battery is transformed into electrical energy, which then powers the light bulb to produce light. This process involves the conversion of stored energy into usable light energy.
