Electricity consists of a stream of electrically charged particles. These particles can be in the form of stored-up energy or they can be in motion and electricity in motion is called electric current.
Electrical engineering is a very broad field. To start with, there is the power engineering, the problems it deals with concern the efficient generation and distribution of electrical power. It is one of the oldest areas of electrical engineering.
The power engineers have to do with many problems, for example, with voltage at which power must be generated, and then there are the problems of controlling the phase, the frequency and the loads of power systems.
More recent fields of electrical engineering are the fields of communications, computers and industrial electronics. The object of communications is to send messages of many types from one location to another. Many new communication devices have been developed recently.
