One of my skills as an engineer is having a modicum of knowledge about circuitry although I do not have an electrical engineering degree. A number of my personal projects have involved electronic systems and I have relied heavily on my study of examples on the internet to complete these electronic projects. One tool I have learned how to use is KiCAD to develop circuit boards and have them manufactured by 'board houses' in and out of the US. As I develop more interesting circuitry both in my employed life and my personal projects, I have realized that a greater knowledge of electronics simulation software would be handy. Therefore, I have dived into LTspice. "spice" is a widely used, free software package that simulates electronic relationships and can evaluate the governing equations of various circuitry components connected together. LTspice is a free software using spice created by the engineers at Linear Technologies (ergo the LT in LTspice).
I have been playing around a bit on a transformer circuit and trying to wrap my head around the various commands and control shortcuts of this software. I wonder what I will use this on next?
