There is no physical connection between the primary and secondary of a transformer. A transformer is essentially 2 laminated coils of wire interwoven with each other. The magnetic field created in the primary coil is induced into the secondary coil creating voltage on the secondary side.
An electric current into a magnetic field
you save energy
a lower voltage into a higher voltage
Electrical energy absorbed by the lamp's filament produces thermal energy as well as light.
Waste to Energy Conversion is when you take waste (the combustible parts of household garbage, for example, that cannot be otherwise recycled) and burn it to run an electricity generator. Then you have used waste to make energy.
an alternator is essentially a generator that converts the kinetic energy from the combustion engine in your car into electrical energy to recharge your battery. To answer your question about connecting a generator to another generator to create limitless energy there is always a loss of energy during the conversion process usually due to friction. In theory it is possible but there is no pure conversion of one form of energy to another in real world application. There will always be a loss of energy in some form.
The conversion of the energy in dirty coal to clean electrical energy which they then export.
Chemical (gas) to thermal (combustion) to mechanical More Simply: Chemical Energy to Mechanical Energy
It stays constant
Kinetic Energy
what type of cell?
Photosynthesis
Static electricity
potential energy
During photosynthesis the energy of light is transformed in chemical energy.
These are the chloroplasts.
Light Energy to Electrical Energy
light energy to elctrical energy
Glucose + oxygen gas -> carbon dioxide + water + energy
Plants convert solar energy to chemical energy.
