I just used a hotpad to pull something out of the oven. The hotpad was a bit wet, and as such, the hotpad was not effective at insulating the heat from the baking tray. This caused an ‘aha’ moment for me, as most things that conduct heat also seem to conduct electricity. There must be a realtionship between the two.
Is there a relationship between the two? And if so, how are they related?

It’s mostly a fluke and based on things we have experience with in our daily lives. Namely metal. Metal has properties that make it great at both, but lots of other less common materials have only one.
Many of things are thermally conductive but great insulators, like oils. Ceramics. Pure water.
You can make things that are super eclectically conductive, like copper, into an insulator by making into a foam with lots of bubbles air or even better, a vacuum.
If you ignore metals you might find there is very little relation between the two.
