Demystifying Electromagnetics, Part 6 – Relays
Over the last 5 blogs in this series we’ve introduced a set of EM building blocks, fundamental behaviours that hopefully have been demystified by the use of analogy. At last, and not before time, we can get on to an actual application – Relays….
Demystifying Electromagnetics, Part 4 – Inductors
Welcome to Part 4 in this blog series that hopes to demystify electromagnetics for those of you who might have a background in mechanical engineering, fluid flow and heat transfer. Ultimately we’ll be getting onto electric motors, generators, induction cooking, levitation, loud speakers etc. etc. but for now some more basics – Inductors….
Thermal Influence on Maximum Current Carrying Capacity
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….
