Eli5 how thermal conductivity and electrical conductivity are related to each other

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?
