Electrical engineering is concerned with the study, design and application of equipments, devices and systems which use electricity. Electricity supplies power to run appliances, heavy machinery, and lights. It also encompasses communications such as the telephone, radio, and television and other consumer electronic devices. And, of course, electronics is changing everything around us every day, through such pervasive devices as hand-held calculators, computers, and controllers that help operate automobiles, airplanes and homes. Electrical Engineering is the largest engineering profession in academic and corporate both.
Electrical engineering is divided into a wide range of fields such as power generation, transmission and effective utilization of electricy. It also involves telecommunications, radio-frequency engineering, signal processing, instrumentation, and electronics. Many of these areas overlap with other engineering branches with a huge number of specializations such as power electronics, electromagnetics and waves, microwave engineering, nanotechnology, electrochemistry, renewable energies, mechatronics, and electrical materials science.
Electrical engineers hold a batchelor degree in electrical engineering and may have professional certification from a professional body. Such bodies include the Institute of Electrical and Electronics Engineers (IEEE) and the Institution of Engineering and Technology (IET) (formerly the IEE). Electrical engineers have the opportunities to work in a very wide range of industries . The tools and equipment that an individual engineer may need are similarly variable, ranging from a simple voltmeter to a top end analyzer to sophisticated design and manufacturing software.
