Electrical Engineering

Electrical engineering became known during the early 16th century. In the early 17th century, it became more popular with the notable contributions of George Ohm, Michael Faraday, and James Clark Maxwell.
It is concerned with the use of electricity to transmit energy. It can include the field of electronic engineering since it also uses power and motor control. It has many sub disciplines such as:
Power engineering which is concerned with the generation, transmission, and distribution of electricity.
Control engineering which is concerned with the modeling of dynamic systems and controllers.
Electronics engineering which is the design and testing of electronic circuits.
Microelectronics which is the fabrication of micro circuit components.
Signal processing which is the analysis and manipulation of signals.
Telecommunications engineering which is concerned with the transmission of information through certain channels.
Instrumentation engineering which is the design of devices that measure pressure, flow, and temperature.
Computer engineering which is the design of computers and computer systems.
Mechanical engineering, on the other hand, has these subdisciplines:
Mechanics, the study of forces and their effect on matter.
Kinematics, the study of the motion of objects and systems.
Mechatronics and Robotics, the design and creation of hybrid systems and robots.
Structural and Failure Analysis, the study of how and why objects fail.
Thermodynamics, the study of energy.
Technical drawing (Drafting) and CNC, the design and creation of products.
Nanotechnology, the creation of microscopic devices.
Mechanical engineering uses physics and science in analyzing, designing, manufacturing, and maintenance of mechanical devices and systems. Mechanical engineers use heat and mechanical power to produce machines and tools.
It developed during the Industrial Revolution of the 18th century and has then evolved into a much broader field as technology advances. It also works together with other engineering fields, particularly with electrical engineering.
