Summary: | Electrical Engineering is concerned with the generation, transmission, and utilisation of electric power and can be roughly sub-divided into two main sections, power engineering and radio communication engineering. The first of theses has been widely developed over the last century and at the present time is not advancing as rapidly as it was, say, twenty years ago. This could be because it is approaching its ultimate, or merely because it is being overshadowed by the more active radio and communications branch. The greatest developments in the power section at the present time are in the field of control equipment such as amplidynes and metadynes.
In the other section the last forty years have covered the advent of radio, television, radar, and world-wide communication systems. In more recent times electronic equipment has been devised for remote and automatic control of many types of machines, both larger and small. These are but a few of the applications of electronics to lighten mans labour and enliven his leisure.
