Electricity
Electricity is the flow of electric charges
Electricity can be transformed into other types of energy such as heat, chemical energy or mechanical energy through energy converters
Electricity is a secondary source
Electricity must be converted from primary energy sources
types of electrical generators used
Electric generators
They supply a large amount of electricity to households and industries
Energy transformation
Kinetic energy to electrical energy
potential energy to electrical energy
Generated from windmills, wind turbines or power stations
Electric cells
Supply a small amount of electricity to portable electric devices
Energy transformation
Chemical energy to electrical energy
Generated from Dry cells, Lithium cells and lead acid accumulators
Solar cells
Supply electricity to calculators or satellites
Energy transformation
Solar energy to electrical energy
Solar panels in calculators and photovaltaics
