Electrical Engineering
Electrical engineering is a branch of engineering that primarily deals with the study, design, and application of systems and devices that utilize electricity, electronics, and electromagnetism. It has a vast array of subfields and applications that impact nearly every aspect of modern life.
History of Electrical Engineering
The history of electrical engineering dates back to ancient times when people experienced the shocks from electric fish. However, it wasn't until the 19th century that the discipline began to take shape with the advent of the telegraph and the electric power systems. Notable figures such as Michael Faraday, who invented the electric motor, and James Clerk Maxwell, known for Maxwell's equations, laid the groundwork for this transformative field.
In the late 19th and early 20th centuries, Thomas Edison and Nikola Tesla made significant contributions, particularly in the generation and distribution of electrical power, which led to the widespread adoption of electricity in homes and industries.
Subfields of Electrical Engineering
Electrical engineering encompasses a variety of subfields, each focusing on specific aspects of the discipline:
