Electrical Engineering and sub-fields

 When we talk about Electrical Engineering and sub-fields we should also know the constituents of the same. It comprises of three sub fields i.e. Electricity, Electronics and Electromagnetism. Today Electronics Engineering and sub-fields has become so vast that it has been segregated from Electrical Engineering. It is again divided into numerous sub-fields which can be classified as Instrumentation, Digital Computers, Telecommunications, Microelectronics, RF Engineering, Power Engineering, Signal Processing and Control Systems

To study the various aspects of electrical and electronics an engineer needs a wide range of test & measuring instruments to analyze and practically visualize various characteristics and studies which have been taught during the course. Some of these widely used instruments are multimeter ( needed for measuring current, voltage and resistance), Oscilloscopes (used for time-varying signals), Spectrum Analyzers & Network Analyzers (study of Radio Frequency Engineering used in mobile phones, radios, Wi-Fi etc.). It is impossible to study of electrical & electronics engineering equipment without using these instruments.
