Coal fired plants, natural gas fired plants, nuclear plants, solar panels, wind turbines, hydraulic generation (dams), etc.
Technically, a transducer is defined as a device, which converts other sources of energy such as heat, mechanical, pressure etc. into electrical energy, i.e., the output of a transducer is always electrical energy. Since, a speaker converts electrical energy into sound energy, it is not a transducer.
Motors convert electrical energy into mechanical energy and generator converts mechanical energy into electrical energy
From electrical energy to mechanical energy
A sound system works by converting sound waves into electrical energy. The electrical energy is then converted back into solid energy that results in sound.
size of the buildng and what the buildings is using to pull on the electrical energy
They are source of electrical energy.
there are not just two electrical sources of energy there are lots but two could be solar and biomass
Is wind and sun a pair of sources of energy
The sources of electric energy are power plants and power generator...
Any voltage source is a potential waiting for a load so that current can flow and "work" can be done. A battery and your power company that supplies your home are sources of electrical potential energy.
lightning
battery
N2 and O2 are the sources of electrical energy. They combine together to form electrical energy.
Alternator
A current in a wire.
The electrical network which has its own energy sources like current or voltage sources within the circuit is called as an active electrical network
light bulbs switches
