DC Theory Topics

From archeological evidence, electricity has been in use in a limited fashion for over 2000 years. Not as a general energy source, of course, but it seems that some cultures used primitive batteries to perform electroplating. Often this was done by the temples, to gold plate religious symbols.

Modern electrical theory was argued back and forth in the mid-1700s, and eventually came together with experiments by Benjamin Franklin and his successors. Since then, much work has been done by many scientists over the years, and our understanding of what electricity is and how it behaves has improved greatly.

Fundamentals of Electricity: The fundamental concepts that form the basis for all study of electricity and electronics.
Resistors: Resistors appear almost everywhere in electronics. Here's a look at what they are, how they are made, and how they can be used in various combinations.
Capacitors: What capacitors are, how they are made, and how they behave in combinations.
Inductors and Transformers: Inductance is the third basic property of electronics components.
Combinations of Components: When components with different properties are combined, the combinations have their own new characteristics.
