Imaginary numbers, or complex numbers, as they are sometimes called, have many intrical uses in our lives, other than confusing students on math tests. They are used in fields such as engineering, architecture, and electricity. I chose to investigate this concept to get a real idea of why anyone would perform equations with numbers that don't even exist. In addition, I also have an inkling of an interest in engineering. Imaginary numbers, despite their departure from existence, can in fact improve our lives in many ways we never though possible. One of those ways is present in almost every room we enter, helping electricians wire our lights and other appliances. The reason behind the use of imaginary numbers is that, when electricity flows through an electrical circuit component, such as a light bulb, it resists the flow of electricity. However, when electricity f
