A lamp doesn't produce electrical energy; it utilises it. The power-rating of the lamp will tell you the rate at which that lamp uses expends energy at its rated voltage. For example, a 60-W lamp will expend energy at 60 joules per second.
With a photovoltaic cell, solar power can be produced
Electrical (electromagnetic) energy is used. Light energy ( another form of electromagnetic energy) is produced.
The useful energy that comes out is light energy. Heat energy is also produced but is not useful
The main purpose of a toaster is to generate heat, not light. A small amount of light may be produced as a by-product, due to the high temperature. The way the heat (and a small amount of light) is produced is simply by using electrical resistors.
The battery produces electrical energy. If the light bulb is connected between the terminals of the battery, then the bulb will change the electrical energy into heat, and if you're lucky and you have the correct voltage, also maybe some light.
In a light bulb, electrical energy is transformed into light energy and heat energy.
TV- Electrical energy to light and sound energy Radio and stereo - Electrical energy to sound energy Fan- electrical energy to mechanical energy Toaster - Electrical energy to heat energy Light bulb- Electrical energy to Light energy Battery or cell - Chemical energy to electrical energy
The produced disappears whether you switch it off or not - otherwise it would get brighter and brighter. In a closed room, the light would eventually be absorbed, and converted to heat. Outdoors, the light may go into outer space, going on and on and on... at a very high speed known as the "speed of light". In general, bet on heat. Light turns into heat.
solar cells are used to change light energy into electrical energy
A solar cell converts light into electrical energy.
Electrical energy is transformed into heat and light. More specifically, electrical energy from the household wiring is turned into thermal energy (heat) by the filament which in turn becomes luminous energy (light). Some energy is lost due to resistance in the conductors.
in a power station, which usually converts chemical potential energy into electrical energy, which supplies potential difference and drives current.
