Electrical and Electronics Engineering
In the field of engineering known as electrical engineering, electricity, electronics, and electromagnetism are studied, designed, and applied to various pieces of machinery and systems. After the widespread adoption of the electric telegraph, telephone, and other forms of electrical power in the latter half of the 19th century, this field began to take shape as a distinct profession in its own right. Computer engineering, systems engineering, power engineering, telecommunications, radio-frequency engineering, signal processing, instrumentation, photovoltaic cells, electronics, and optics and photonics are just a few of the many subfields that make up modern electrical engineering. Hardware engineering, power electronics, electromagnetics and waves, microwave engineering, nanotechnology, electrochemistry, renewable energies, mechatronics/control, and electrical materials science are some engineering subfields.
