Paper format. PEO / Engineers Canada National Examinations, December 2019 — 16-Mec-A5, Electrical & Electronics Engineering (Mechanical Engineering discipline). Three hours, closed book, one approved Casio or Sharp calculator. Eight questions; any five constitute a complete paper and each question is of equal value, so each counted question carries 20 marks. All eight questions are solved below, because this set is a study resource rather than an exam script. The front page prints the constants $\pi = 3.14159$, $1\text{ hp} = 746\text{ W}$ and $\mu_0 = 4\pi\times10^{-7}\text{ H m}^{-1}$; all three are printed clearly on the front page and are used exactly as given.

the gated-logic array, the transformer magnetic circuit, the op-amp band-pass Bode question, the RC transient and the parallel ac network as printed in December 2014; and the induction-motor slip / speed-torque question as printed in December 2016. The full working is transcribed in place below rather than cross-referenced, so this paper stands on its own as a study document.
