MITx Circuits & Electronics [1][2][3] (it's in 3 parts) MOOC. They are just starting a new instance today, so your timing is perfect.

This is a seriously good course. I've been interested in electronics on and off since I was a kid. I tried learning from various Radio Shack books, but never got very far. I tried some introductory classes at Caltech, and never got very far. Tried "The Art of Electronics" and it just didn't work.

That MITx course worked.

That said, it does get fairly mathematical...circuits involving inductance and capacitance are going to be analyzed using differential equations so if you have never had any exposure to such things it could be rough going.

If you've been through college calculus you should be fine, even if (like me) you've forgotten most of it. They have some refresher material that should bring enough back to get through it.

Here's what you learn in part 1:

• How to design and analyze circuits using the node method, superposition, and the Thevenin method

• How to employ lumped circuit models and abstraction to simplify circuit analysis

• How to use intuition to solve circuits

• Construction of simple digital gates using MOSFET transistors

• Measurement of circuit variables using tools such as virtual oscilloscopes, virtual multimeters, and virtual signal generators

Part 2 teaches:

• How to build amplifiers using MOSFETs

• How to use intuition to describe the approximate time and frequency behavior of first-order circuits containing energy storage elements like capacitors and inductors

• The relationship between the mathematical representation of first-order circuit behavior and corresponding real-life effects

• How to improve the speed of digital circuits

• Measurement of circuit variables using tools such as virtual oscilloscopes, virtual multimeters, and virtual signal generators

• How to compare the measurements with the behavior predicted by mathematical models and explain the discrepancies

Part 3:

• How to construct and analyze filters using capacitors and inductors

• How to use intuition to describe the approximate time and frequency behavior of second-order circuits containing energy storage elements (capacitors and inductors)

• The relationship between the mathematical representation of first-order circuit behavior and corresponding real-life effects

• Circuits applications using op-amps

• Measurement of circuit variables using tools such as virtual oscilloscopes, virtual multimeters, and virtual signal generators

• How to compare the measurements with the behavior predicted by mathematical models and explain the discrepancies
