Electrical engineering develops electrical and electronic systems for public, commercial, and consumer markets. It is tremendously broad, spanning many domains including recreational electronics, residential lighting, space communications, and electrical utilities.

What are the detailed design features of the system that best satisfy the stated mission or market requirements? How will we conceive, design, implement, and operate electrical and electronic products and systems?

Electrical engineers employ experimental and computational data, legacy designs, regulatory requirements, market studies or mission needs statements.

The conclusion of most electrical engineering activity is a product ready for delivery to a customer.

These concepts include electromagnetism (Maxwell’s equations), electrochemical properties of materials, discrete and analog mathematics, resistance, current, charge, voltage, fields and waves, and so on.

Assumptions are in part shared by all scientists and engineers. One assumption is that the universe is controlled by pervasive laws that can be expressed in mathematical terms and formulas, and that those principles can be used to model electrical systems. Electrical engineers assume that some important market needs can be best met through electrical and electronic products. Additionally, electrical engineers frequently assume that their work must be integrated with other engineering disciplines (such as mechanical, chemical, and so forth) in the design and implementation of a product.

Electrical engineering products and services have wide-ranging implications that span global, national, and local economics, public infrastructure, health care, and communications, with potential for positive and negative quality of life impacts on communities and regions.

The point of view is commonly that of the design and manufacturing team. Other relevant points of view include the customer, stockholders, marketing, maintainers, or operators.
