Recently, rummaging through an old briefcase I found myself staring at a 50-year-old notebook. The diagram displayed is a page of my studies in Electrical Theory (AC, DC, V, R, Z, C, I, etc.) and its mathematical characteristics. Little did I know then, I’d be sharing a sample of this material to the world. The basic electrical/electronic theory is still the same, but the means of implementation was beyond conception/comprehension 50 years ago.
