Electrical Engineering Interview Questions

Electrical engineering is an engineering discipline that deals with the study, understanding and application of electronics, electricity and electromagnetism. This field has become a specialized occupation during late 19^thcentury following commercialization of electrical power and electric telegraph supply. Electrical engineering today includes a wide variety of subfields, such as electronics, power, signal processing, telecommunications and control systems.

This field of engineering is considered to be dealing with the issues associated with systems like electrical machines and power transmission.
