Power is energy per unit time, or the rate at which electric energy is transformed. The amount of energy transformed is therefore power multiplied by time. (The above assumes that power remains constant over the time considered. If not, advanced math - derivatives and integrals - must be used instead.)
Light is a form of electricity with a high frequency vibration.
I don’t know
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.
The more electrical energy there is there is more power or wattage which means that the light intensity is higher if there is more electrical energy.
light bulbs switches
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

Electrical energy gets converted to light and heat energy.
The older generation of bulb(one in witch heating metal coil was used) convert electrical energy into both heat and light energy and consume more energy as some energy is lost as a heat energy. The newer generation of electrical bulb (C.F.L.) convert almost all electrical energy into light energy and consume much less electrical energy.
Yes, electrical energy can be changed into thermal (heat) energy. Light is electromagnetic energy, and electricity can be changed into light energy. We know that a resistance heater changes electrical energy into thermal energy. An electric range does this, as does an electric space heater. We see electrical energy changed into light in fluorescent lights.
silicon solar panels that convert light energy to electrical energy. they are known as photo diodes
