content: I am 58 years old, and have just started studying electronics! I’m hooked after looking at Martin lorton and Dave Jones no bulkshit Approch.I believe that the previously unfathomable magic of a circuit board is now being demistified after a period of deliberation lot of u tube videos my strategy is to immerse myself in PCB repaires( no previous experience )and in parallel stud circuits and associated maths that’s my question reall y what are the core basic maths subjects I need to know definitive list. ? with exercises worked example can anybody help I don’t know ifI have the ability to grasp the maths but I will die trying I want to go to my grave understanding electronics ! its haunted me for so many’s year I have a succcesful marine business And I can afford the kit but I know it’s not about that !!! I I am smitten I may go all the way who knows any help would be really good x

content: Algebra. Lots of Algebra . Ohms law is a good start . Just remember that every complex circuit is made with many simple circuits. By understanding the simple circuits everything else starts to make sense.

content: A graet tool to gain an understanding of circuit behaviour is LTSpice, which is free and you find a ton of tutorials as well as pre buitlt circuits in the examples folder.https://www.analog.com/en/design-center/design-tools-and-calculators/ltspice-simulator.htmlIt's a bit of a pain in the neck to get started with it - but once you learned a few tasks you can start doing simple operations with it...Note that modelling circuits means to (over-) simplify them. That means to be prepared for a few surprises, because you won't be able to anticipate eveerthing that matters.On the other hand side you can isolate principles to study them without being challenged with overlapping effects...

content: I would recommend starting with two great books by author Thomas L. Floyd. When I wanted to get back into electronics I did an extensive search for the best books, and here they are:1. Principles of Electric Circuits: Conventional Current Version (10th Edition) by Thomas L. FloydISBN-13: 978-0134879482ISBN-10: 01348794812. Electronic Devices (Conventional Current Version) (10th Edition) by Thomas L. FloydISBN-13: 978-0134414447ISBN-10: 9780134414447

content: There are a few books out there I've looked at that have seemingly no actual troubleshooting in them and more how to use a multimeter and solder etc.I'm yet to find material that really conveys the repair process well or a comprehensive list of building block circuits with functional descriptions. I think this would be a great aid in teaching electronics and repair quickly.These are some of books on troubleshooting that are actually worth owning, they all have examples and work through actual circuits. Though they are a bit old they are comprehensive and the knowledge can be applied today. You only need some basic algebra and ohms law to get started.Electronic Troubleshooting - Jerome E OleskyTroubleshooting Solid State Circuits - George LovedayElectronic Testing and Fault Diagnosis 3rd Ed. - George LovedayElectronic Fault Diagnosis - George Loveday

content: The two Thomas L. Floyd books mentioned in a prior post contain troubleshooting sections as well as application activities using DMMs, oscilloscopes, etc.
