A flow of electricity that moves in one direction only

The highest point reached by something

A flow of electricity that regularly changes direction

Renewable energy sources can best be defined as

resources that will regenerate in a generation or less

resources that will regenerate in a million or more years

resources that will regenerate in 10-20 million years

resources that do not have the ability to regenerate

Energy production in thermal power plants as well as with hydroelectric, wind and wave or tidal power all produce electricity by

turning a turbine that runs the generator to make electricity that is taken to homes and businesses through transmission lines

the energy source directly runs the generator that then turns a turbine which produces the electricity that is taken to homes and businesses through transmission lines

the energy source is converted by a heater then the electricity is sent out to the homes and businesses through transmission lines

the energy source is used to power batteries that store energy, when you flip on a light or run electricity at your home, the battery sends the energy through transmission lines.

The main problems in transmitting the electrical current are:

E) high resistance and current in transmission cables

high voltage in the transmission cables

high current in the transmission cables

high resistance in transmission cables

high resistance, current and voltage in transmission cables

National Grid Network consists of
