Answer 1

Answer:

Dynamo:- mechanical energy into electrical energy

Nuclear power reactor:- Three mutual conversions of energyforms occur at nuclear power plants:nuclear energy is converted into thermal energy, thermal energy is converted into mechanical energy, and mechanical energy is converted into electric energy. ... This is how the most difficult conversion (nuclear into thermal energy) is carried out.

Solar cell :- The two main forms of solar energy transformation technologies are photovoltaic (electricity) and thermal (heat).

Thermal power plant :- energy, which in turn is converted into electricalenergy

Battery :- A battery is a device that stores chemical energyand converts it to electrical energy

Water flowing across a dam :- As the water flows downthrough the dam its kinetic energy is used to turn a turbine. The generator converts the turbine's mechanicalenergy into electricity.
