One thing I have always thought that experienced repair people knew about was circuit analysis. I always imagined that when looking at schematics I would be able to figure the voltages at any node and if a particular node was zero volts, lower than expected, higher then expected or the same as the supply voltage I would know what component was most likely at fault. I have been study circuit analysis and it is not an easy thing to grasp and I still have a ways to go, but am I fooling myself? and isn''t there an easier way to learn this subject?
Most of the books are teaching this to engineering students, but I only want to learn this for repair work. I don''t need exact answers just close enough to for me to see that there is a problem with a component. Are there any books or websites that teach this subject to repair people? Something that can show us shortcuts for figuring these things out? Can this even be done? Can this subject be streamlined so that general rules of figuring voltages can be learned quickly?
