Electrical engineering: AC analysis intro 2

Here's a preview of how AC analysis is going to work. To get ready we need to review some of the ideas from trig and complex numbers.

Electrical engineering

Learn about electricity, circuit theory, and introductory electronics. We also have sections that let you get down and dirty with household items, from building your own robot to videos where we disassemble household items to see what's inside.

AC circuit analyisis

If we limit ourselves to input signals shaped like sines or cosines, we can develop a whole AC analysis method to figure out what happens in circuits with changing signals. The methods are far simpler than solving a differential equation.
