Demystifying Electromagnetics, Part 2 – Wires

March 12, 2021

Ohm’s Law is just a flow rate, analogous to fluid mass flow. What’s that got to do with EM and what is Temperature and Joule heating anyway?…

Demystifying Electromagnetics, Part 1 – Fields and Analogies

March 2, 2021

This blog series will strive to demystify (low frequency) EM by way of pictures and analogies, with as few equations as possible, by introducing a series of applications of increasing complexity. In this first blog we’ll and start to look into the electric field with the use of some analogies….

Thermal Influence on Maximum Current Carrying Capacity

January 20, 2021

Superconductors aside, anything that conducts electricity will dissipate heat. The more current that flows, the more heat is dissipated, the hotter things will get. At some point a thermal limit is reached that imposes a maximum current carrying capacity constraint….
