Electrical engineering is a field of engineering that generally deals with the study and application of electricity, electronics, and electromagnetism.

Instrumentation engineering is the engineering specialization focused on the principle and operation of measuring instruments that are used in design and configuration of automated systems in electrical, pneumatic domains etc.

Safety engineering is an engineering discipline which assures that engineered systems provide acceptable levels of safety. It is strongly related to industrial engineering / systems engineering, and the subset system safety engineering.
