CHAPTER 1 WHAT DO ELECTRICAL ENGINEERS DO Look at all the machines in your house that use electricity There are computers televisions and lights They may be plugged into an electrical socket in the wall or they may use batteries Either way electrical engineers helped to make each one Electrical engineers design build and fix machines that use electricity How many electrical devices can you spot in this kitchen
There are many different types of electrical engineering Some engineers work on improving how electricity is made or delivered to your home Others design electric motors or the electrical systems in computers Some specialize in medical equipment If designing or testing electrical devices sounds like fun electrical engineering could be the field for you But you don't have to wait to get started WHAT IS ELECTRICITY Electricity is the flow of electrons or electrical charge Lightning is an example of a natural electric flow Electrical charges move along materials called conductors Many metals conduct electricity Electrical engineers learn how to harness the power of electricity and make it do useful work Electrical cords contain metal wires that conduct electricity electron a tiny particle in an atom that travels around the nucleus conductor a material that lets heat electricity or sound travel easily through it
