Maybe the Khan Academy Electrical Engineering curriculum can be useful:
https://www.khanacademy.org/science/electrical-engineeringBeing capable of solving book problems is a good start. How many lab experiments did you actually build up? Yes, the explanations and all of the math are helpful but until you see the experiment output on a DMM or scope, it's just ink on a page (or pixels on a screen...)
There is nothing I can do about the price but I still highly recommend the Digilent Analog Discovery 2 as a reasonably complete lab in a tiny box. You can do a lot of EE experiments with this gadget. See the attached Bode' Plot. That is the result of a 10k resistor in series with a 0.1 ufd ceramic capacitor with the AD2 providing the swept frequency and measuring the resulting voltages.
The second graph is the forced response when an 83.333 Hz square wave (f=1 / 12 ms) of 1V p-p forces a response on the same resistor/capacitor combination. The cursor is at 1 Tau and the output is about 65% (in a perfect world with no component tolerances, this would be around 63.2%. The square wave is high for 6 Tau (6 ms).
These are simple experiments and are adequately covered in every textbook but, for me, seeing the waveforms is a lot more useful for learning.
A close cousin to actually building circuits is using a simulator like LTspice. I attached a plot for the very same forced response. As useful as it is, it's still not parts and wire.
BTW, notice that I charged the capacitor for 6 ms which is 6 Tau which results in a charge of 99.75% of Vin so the square wave covers 12 Tau - 6 Tau to charge and 6 Tau to discharge. You can calculate Tau as R * C or (10
4 * 10
-7 = 10
-3 or 1 ms)
