M*A*T*H Colloquium: Electric Power and Complex Numbers: Imaginary Axis to the Rescue!

Mar 8, 2023 , 4:00pm
Darwin 103 or Zoom
Math & Statistics Department

Sascha Von Meier, Independent Consultant

This talk will introduce complex numbers as a tool for the analysis of electric grids. Mathematically, alternating voltage and current from the wall outlet looks approximately like a sine or cosine—but with some important caveats. We will encounter Euler’s formula, phasors, and techniques for manipulating quantities like electric power transfer with convenient shortcuts. We’ll also highlight some of the surprises that can occur when the physical world doesn’t quite match the idealized mathematical model.


Zoom Link for Spring 2023 M*A*TH Colloquium Talks (Zoom will open at approximately 3:45 before each talk)

The M*A*T*H Colloquium is our weekly public lecture series. Talks are on Wednesdays at 4:00 p.m. in Darwin 103 and on Zoom; see link above (first four talks are on Zoom only). Maps to and of campus are available. A parking permit is required to park on campus, and is available for $5.00 at machines in the parking lots. Talks are otherwise free.

The M*A*T*H Colloquium has been in operation during every semester since Fall, 1974. See below for previous posters.
