content: Is there a workbook of basic circuit analysis problems with solutions? I have completed a number of lectures up to Thevenin/Norton and Superposition and would like to strengthen my confidence.I searched w/Google to no avail. Practice exams w/no solutions are no help. My basic failing is that I get correct solutions but I frequently miss the obvious easy solution. This is an experience issue.I do check my answers against a breadboard setup, but it would go faster if I could compare my solution against solutions in the back of the book.Thanks.Regards,Dewey

content: You can check the solution manual for the book Electronic Devices and Circuit Theory by Boylestad/Nashelsky.

content: As in the example you posted earlier, Many textbook examples are purposely drawn in a confusing way forcing you to examine the layout and see if through intuition you can reduce the circuit to simple terms then solve the problem. Intuition is hard to teach and comes more from experience. In the real world you won't run into easy circuits purposely draw in a difficult to understand way. Thevinin and Norton you won't experience unless you are into some high level design stuff or power grids and power grid current flow from multiple suppliers can be ugly due to leading / lagging phases and power factor. In theory a customer with a poor enough power factor could melt 14 gauge copper wires and yet only be showing a 100 watt load. Sadly, I can't think of any textbook on resistive circuits that will help teach intuition. I taught it with a blackboard (which was really green) and chalk. I would draw a stupid circuit and then help my junior co-workers work through it. Eventually they gained confidence and scary looking circuits no longer scared them. Think about some visual examples where you inherently already know the math and the answer pops into your head without hardly any thought. Example two 10 ohm resistors and a 5 ohm resistor all in parallel. I take one glance, the two 10's in parallel = 5 ohms which is in parallel with another 5 ohm so the answer is 2.5 ohms. This is how I taught parallel circuits. A student can understand how to solve the circuit without me using oddball combinations. As always they must understand R1 X R2 divided by R1 + R2. Another one is a 10 ohm resistor paralleled with a 5 ohm resistor. When ever I see that 2:1 ratio I know the answer is .666 X the lower resistor value. Intuitive? Best wishes, Cheers mate!!

content: I bought the Boylestad books (Texts and Labs). I bought both the Ckt Analysis and the Devices books.Thank you for recommending them, they are precisely what I was looking for. Not only step by step, but lots of practice at reducing "actual" circuits, not just simplified circuits to be solved. This is giving me the experience I sought.These are not cheap books, but can be found used.His comparison of series resistance parameter functions to parallel resistance functions (he calls it duality) simplifies what I have to keep in my head.I definitely recommend these well before Art of Electronics for someone who wants to understand the foundations of electronics before putting together a set of devices. And forget NEETS! (But Dave's EEVblog videos and the Real Analog lectures are useful).Thanks again!Dewey
