Electrical engineering covers a wide range of topics, from the simplest circuit to the most advanced super-computer. The main courses an electrical engineer must take are: circuits, electronics, digital design, and microprocessors. The skill electrical engineers have can be used in a wide variety of ways. Main areas that an electrical engineer can work in are: telecommunications, energy and electric power, computers, semiconductors, aerospace, bioengineering, manufacturing, services, education and research, and transportation and automotives.

The main mathematics of electricity is based off of two very important laws, Ohm's law and the "Power Law". Ohm's Law is used for the relationship between Voltage, Current, and Resistance. The "Power Law" is used for the relationship between Power, Current, and Voltage. These laws can be used together to analyze the properties of electrical circuits.

Electrical Engineering uses binary logic to make electrical circuits perform tasks such as computing. Binary logic basically consists of sets of statement that can either be true or false. These statements are related by three simple operations, AND, OR, and NOT. Electrical circuits can use binary logic to answer problems. For example: The statements: A person is in the passenger seat, The car is turned on, and The passenger seatbelt is fastened, can all be true or false. An electrical circuit can analyze these true or false statements and decide whether or not the fasten seatbelt light should be on.

Electrical Engineers are constantly trying to find ways to make circuits smaller, faster, more efficient, and more reliable. Technology has advanced greatly since the fist computer. The integrated circuit has allowed computers to become much smaller. Since the invention of the integrated circuit in the early 1960's computers have been becoming faster and smaller at a constanly increasing rate.
