One of the largest branches of engineering: The electrical and electronics engineers specialize in design and development of electrical and electronic equipment and products.

• They work with power generation and transmission; machinery controls; lighting and wiring for buildings, automobiles, and aircraft; computers; radar; communications equipment; missile guidance systems; and consumer goods; such as, television sets and appliances.
• They may specialize in communications, computers, or power distribution equipment, or in a subdivision; such as, aviation electronic systems or in the research, development, and design of new products.

A specialist who develops methods to process and convert metals and other materials into usable forms: These metallurgical engineers develop new materials for applications that require exceptionally high strength and heat resistance and they also determine how materials fail, using instruments; such as, microprobes, scanning electron microscopes, and X-ray diffraction and examine failed, broken, or contaminated materials.

Technology is developed to produce ceramic substances, new compounds, and metal alloys for use in computers, spacecraft, and industrial equipment.
