What is electrical engineering

Understand motion magnification, a technique enabling researchers to monitor tiny vibrations in infrastructure engineering, the application of engineering is sometimes more loosely defined, especially in Great Britain, as the manufacture or assembly of engines, The words engine and ingenious are ingenerare, which means “to create.” The early English verb engine meant “to contrive.” Thus, the engines of war were devices such as Associated with engineering is a great body of special knowledge; preparation for professional practice involves extensive training in the application of that knowledge. Standards of engineering practice are maintained through the efforts of professional societies, usually organized on a national or regional basis, with all members acknowledging a responsibility to the public over and above responsibilities to their employers or to other members of their society. The function of the scientist is to know, while that of the engineer is to do. Scientists add to the store of verified systematized knowledge of the physical world, and engineers bring this knowledge to bear on practical problems. Engineering is based principally on Unlike scientists, engineers are not free to select the problems that interest them. They must solve problems as they arise, and their solutions must satisfy conflicting requirements. Usually, Engineers employ two types of natural resources—materials and energy. Materials are useful because of their properties: their strength, ea...

Successful students will need to have a strong grasp on computer programming, numerical analysis, engineering mechanics, and materials. Electrical engineers use these problem solving techniques to research, design and develop computers, electrical devices, communication, and robotic systems. What do Electrical Engineers do? Electrical Engineers design, manage, and develop new electrical devices and equipment. Engineers can work on a broad range of things. Ranging from navigation systems, supercomputers, or house wiring. A degree in electrical engineering qualifies you for a job in almost all industries. Seeing as though most industries use electrical devices in someway Electrical Engineers are a necessity. Electrical engineers also heavily rel...

Engineers at the Massachusetts Institute of Technology (MIT) have successfully created a one-megawatt motor which is a crucial stepping stone in making large electric planes in the future. The team has tested individual components of the motor and computed to show that it can generate one megawatt of output, a press release said. With the world focused on reducing its carbon emissions to "net zero" by 2050, aviation is a sector that needs maximum innovation to achieve this target. Large aircraft that haul passengers and cargo today also have large carbon footprints. However, solutions for the electrification of aviation are still small and incapable of replacing large jet engines. Attempts at making fully electric planes are usually small. The motors used to propel them can only generate a few hundred kilowatts of power at a time. Large aircraft demand larger output from the motors, so MIT engineers set out to develop a one-megawatt electric motor. Why electric airplanes are still small? To understand the difficulty in making a megawatt electric motor, one first needs to understand how an electric motor works. Conventionally, electric motors use electrical energy to generate a magnetic field - typically by sending current through copper coils. A magnet placed near the coils spins in the direction of the magnetic field generated and drives a fan or a propeller with it. Larger copper coils must be used to generate All these components add to the weight of the motor, making i...

What is an Electrical Engineer? Electrical engineers specialize in designing, developing, and testing electrical equipment and systems. These systems can include everything from large-scale power grids and communication networks to smaller electronic devices such as smartphones and laptops. Electrical engineers work on a wide variety of projects and are responsible for ensuring that the electrical systems they design and develop are efficient, safe, and reliable. Electrical engineers must have a strong understanding of mathematics, physics, and computer science, as well as excellent problem-solving skills and attention to detail. They work in a variety of industries, including telecommunications, power generation and distribution, electronics, and manufacturing, among others. In this article: • • • • • • What does an Electrical Engineer do? Electrical engineering is a crucial field that plays a vital role in shaping the world we live in today. Electrical engineers design and develop the technology and infrastructure that powers modern society, from the electrical grids that power our homes and businesses, to the electronics and telecommunications systems that connect us to one another. Duties and Responsibilities The duties and responsibilities of electrical engineers can vary depending on their specific job and industry, but some common responsibilities include: • Designing and developing electrical systems: Electrical engineers work to design and develop electrical syste...
