What is electrical engineering?
Electrical engineering is the science that deals with the use of electricity for performing work. This field includes the design, production, and maintenance of machinery that use the electrical force to perform tasks. The goal of the field is to create machines that are capable of performing tasks that we are not able to perform with the help of our own physical abilities. This includes creating machines that are capable of producing a current, voltage, or resistance.
Why is electrical engineering important?
The world is becoming more and more dependent on electricity. In fact, more than 50% of the world's population now lives in regions that do not have a reliable electricity supply. In these regions, the only option is to rely on a power company. The problem is that power companies are not always reliable. In fact, there are times when they fail. In these cases, it is important to have a backup plan in order to be able to provide electricity when needed. It is also important to develop technologies that are capable of saving electricity.
