Electrical engineering is defined by activities that include research, education or design functions that depend in some fashion on electrons and photons. Electrical engineering is an exciting field of study with a broad scope and significant impact on modern society. Almost every technology in history that distinguishes the 20th and 21st centuries has the imprint of electrical engineering - electric power, radio, television, radar, satellite communication, global positioning systems, medical diagnostic and procedure systems, sophisticated domestic appliances, cell phones, computers, and sophisticated sensors and control systems used in under water, space exploration and national security. Electrical engineering has indeed advanced national and global prosperity by research, development and application of electrical and information technologies and sciences for the benefit of humanity and has helped create the global village.

"research, engineering design, technical sales, system operation, education or management: Research engineers apply laboratory science and mathematics to real-world problems. Design engineers make laboratory prototypes into useful products. Sales engineers use engineering know how to understand and help satisfy the technical needs of their customers. System engineers operate and maintain electrical systems or provide technical support to customers"
