Electrical Circuits: Harnessing Electricity (Exploring Science: Physical Science)

Electricity is a necessity in today’s modern society. It allows us to check our email, watch a movie on the television set, or turn on a lamp at the flip of a switch. But how does electricity work? Atoms contain negatively charged particles called electrons. Electric energy from the electrons can be harnessed into currents that run through two types of circuits—series and parallel. Generators and different types of power plants produce the electricity needed to operate our technological world.
