It's a subject very close to mine as well! I cut my teeth on their form of electronics when I was a teenager and then went on to read the subject to get an honours degree in it in the mid 60's from what was then THE university electronics department in the country (and I only was required to get 3 "C's" at A level to get in as well - says something for todays standards don't you think).
All commercial pilots are required to have a basic knowledge of electricity and ohm's law to pass their exams. In certain cases it isn't too good and I used to get much pleasure in improving this by discussions with some of my FO's in the cruise at FL 300!
P.P.
