a: The electrical energy ~
b: sound waves which fly through the air
What: "If this is confusing, consider sound waves which move through collections of air molecules. Electricity is like the air which is vibrating, while the electrical energy is like sound waves which fly through the air. Sound and air are two different things, just as energy and electricity are two different things."
