comment Power dissipated on internal resistance of short-circuited voltage source
When you calculate the power dissipated due to heating of the internal resistance when shorting the battery, you have to use the EMF $$\mathcal{E}$$ of the voltage source in your third equation, not the nominal battery voltage external to the internal resistance, $$V$$, as you have done. It then agrees with your final equation, and there is no contradiction.

comment Boundary conditions for 2D helical waveguide
@WetSavannaAnimalakaRodVance Wow, that's interesting. Do you have any references from that time period detailing these plans? It would make a really interesting read. Thanks again for the references on the helical waveguides - the math seems fairly involved so I will have to do some review of EM topics before I can fully understand them.
