Electrical engineering

What does an electrical engineer do? "Electrical engineers design, develop, test and supervise the manufacturing of electrical equipment, such as electric motors, radar and navigation systems, communications systems and power generation equipment, states the U.S. Bureau of Labor Statistics. "Electronics engineers design and develop electronic equipment, such as broadcast and communications systems — from portable music players to global positioning systems (GPS)." If it's a practical, real-world device that produces, conducts or uses electricity, in all likelihood, it was designed by an electrical engineer. Additionally, engineers may conduct or write the specifications for destructive or nondestructive testing of the performance, reliability and long-term durability of devices and components. Today’s electrical engineers design electrical devices and systems using basic components such as conductors, coils, magnets, batteries, switches, resistors, capacitors, inductors, diodes and transistors. Nearly all electrical and electronic devices, from the generators at an electric power plant to the microprocessors in your phone, use these few basic components.

Become familiar with engineering numbers and notation, and learn about the two most important electrical quantities: current and voltage. Getting started Circuit analysis 0 of 93 complete Circuit analysis is the process of finding all the currents and voltages in a network of connected components. We look at the basic elements used to build circuits, and find out what happens when elements are connected together into a circuit.
