They can all be used to power automobiles

They are all sources of direct current

They are all sources of alternating current

They all produce static electricity

It is a source of electromagnetic radiation

It is a source of direct current

It is a source of alternating current

It is a source of static electricity

Direct current always flows in the same direction; the direction of an alternating current switches back and forth

Direct current produces more voltage than alternating current

Alternating current produces more voltage than direct current

Alternating current always flows in the same direction; the direction of a direct current switches back and forth

It travels through the air as electromagnetic waves

Through a series of generators

Through transmission wires

Through a series of many transformers

It is often produced by burning fossil fuels, which are a polluting, non-renewable resource.

Using too much electricity can cause power plants to break down.

Using too much electricity can start dangerous electrical fires.

Power companies only give each home a limited amount of electricity every day.
