I started on this above: What does "Learn Electronics" mean to you?
If you want to know enough to copy and paste projects, a few simple concepts like those I posted above are all you need. You could probably even derive some circuits from prior art with no formality at all.
If you want to know it like an EE, sit down, strap in and get ready for 5 years of no sleep and math spilling out all over the floor. Not highly recommended unless you want to work in the field. And it really isn't necessary for the hobbyist.
If you want to see some easy EE classwork, look into Khan Academy Electrical Engineering or Digilent's Real Analog course.
Watch Dave's "Fundamentals Friday" series. These are excellent and far too few. We need more "Fundamentals Friday" videos!
Seek out w2aew's videos on all sorts of things. He also does an excellent job of presenting electronics.
Of course, there are hundreds of other sites about which I know absolutely nothing.
In some ways, there is a difference between the goal of 'learning electronics' and 'building electronics'. By that, I mean the 'learning electronics' will be spent breadboarding educational experiments that have no particular end use. Everybody knows the equation for a charging capacitor but not everybody has taken a resistor, capacitor and square wave and watched the charge and discharge waveforms on a scope. That's 'learning' in my view. Or, plug in a sine wave and do a Bode' Plot to see how a low pass filter really works. Not mathematically works, not hand-wave works, how it truly works. Breadboarding and testing is learning!
There's a reason for all that differentiation: I want to suggest you put ALL of the test equipment, other than a couple of Aneng AN8008 DMMs, on hold and consider the Digilent Analog Discovery 2 and the education kit. Sure, it's expensive but nowhere near what it would cost to outfit a lab with similar discrete tools. Couple it with the Digilent Real Analog course if you wish. Dave has done a video on the AD (the earlier model) and I use mine all the time when I want to demonstrate some concept like the frequency spectrum of a square wave like I did on a different thread earlier today. If I want to play with a transistor amplifier, the AD2 has differential inputs which makes it easy to measure certain voltages that aren't ground referenced. Like measuring the collector or base current by connecting the differential inputs directly across the collector or base resistor. There are other ways to do it but none are as clean as using the differential inputs of the AD2.
As to the AN8008s, there is concern that the CAT ratings are bogus. It is recommended to avoid using them on mains voltages. Dave's meters are several levels more highly respected. I have both and they are excellent but the 121GW is pretty pricey. The BM235 is also a very nice meter. Over in the Test Equipment forum there is a lot of information on DMMs - look at the 'stickies'.
The newer version has adjustable supplies (up to 5V) and the software is much more sophisticated. You can actually download the Waveforms software and run it is Demo mode with no device attached. Just to get a feel for things.
