Previous tutorials have shown the properties and characteristics of simple resistor-only and inductor-only AC circuits. We will now investigate the effects of combining the two components together.

You can make all sorts of different types of inductors, but the most common type is cylindrical coil of wire---a solenoid. When current runs through the first loop, it creates a magnetic field that ...

If you have ever read advanced textbooks or papers about electronics, you may have been surprised to see the use of complex numbers used in the analysis of AC circuits. A complex number has two parts: ...
